Best Fuel Filter for 6.7 Cummins

The best fuel filter for 6.7 Cummins beats their stock counterparts on every count. These products last longer than their peers that came pre-installed in your vehicle, require relatively less maintenance, and resist damage caused by extreme driving conditions better. And they don’t stop at that.

Such products are incredibly efficient at capturing contaminants from oil as well. They also have seals on both ends that keep them from collapsing under pressure. The design of their filtration media, meanwhile, allows them to boost longer oil change intervals.  

On top of everything else, these units help prevent dry starts. They do that via an anti-drain-back valve that keeps fuel from making its way back into the crankcase as you shut the engine. Little wonder, then, that these models are incredibly popular on the market.

Fleetguard LF16035 Oil Filter

Fleetguard LF16035 Oil Filter

Multiple features of this oil filter make it a trustworthy option. Start with its filtration media. The ‘StrataPore’ media improves filtration and its multi-layer organic containment provides longer filter life and more efficiency. And it doesn’t stop at that.

It is also strong and durable and poses no restriction in the way of clean fuel. The huge filtration capacity of the media, meanwhile, allows for thousands of miles of oil change intervals. It means you can drive for years without worrying about the health of this filter.

Yet another feature of this unit that impressed is its compatibility. Fleetguard has kept its design more or less the same over the years. That’s why it fits seamlessly in all Dodge RAM pickups manufactured between 1989 and present. You can also use it with all Cummins Turbo Diesel engines.

That isn’t to say that this oil filter offers universal compatibility. Ram 3500 drivers have complained that the absence of a rubber seal means they cannot use it in their vehicle. You may want to keep this fact in mind if you too drive the same vehicle.

Pros

  • Patented filter media
  • Multi-layer filtration
  • Allows for longer oil change intervals

Cons

  • Might not fit the Ram 3500

WIX Filters - 57620XP Xp Spin-On Lube Filter

WIX Filters - 57620XP Xp Spin-On Lube Filter

Here is another affordable oil filter that hasn’t cut any corners to keep its price low. The 57020XP is a must-have for engines that harbor synthetic oil. It prevents oil clogs by trapping up to 100 percent of particulate matter that may have entered the filter alongside the fuel.

Another way this product belies its meager price tag is by resisting damage. It doesn’t allow extreme driving conditions and elevated oil temperatures to get the better of the engine. That it does via its fully synthetic media which prevents this filter from collapsing under pressure.

This oil filter also has a specifically formulated HNBR gasket. It not only resists the hardening of the filter media at elevated oil temperatures but also provides a foolproof seal during frigid conditions. This is how this unit keeps cold engine starts at bay.

Most filters that you see on the market encourage dry starts past their oil change interval. This one doesn’t. Its silicone anti-drain-back valve keeps a lid on such shenanigans. Perhaps that’s the reason why WIX filters have equipped this model with a full manufacturer warranty. 

Pros

  • Resists hardening of the filter media
  • Traps up to 100% of particulate matter
  • Comes with a full manufacturer warranty

Cons

  • May ship alongside a dirty filter

K&N Premium Oil Filter

K&N Premium Oil Filter

Multiple features of this oil filter make it hard to ignore. Start with its ability to ensure high oil flowrate. This unit is designed to provide a consistent and exceptionally high-flow rate at all times. It doesn’t have any unnecessary bends that could slow the oil down on its way to the engine’s inlet.

Next comes its versatile compatibility. Most oil filters on the market work with either conventional or synthetic motor oils. A sizable minority lets you use blended motor oils too. This oil filter, meanwhile, works with all three (conventional, synthetic, blended) motor oils.

K&N has left no stone unturned to make this model long-lasting. It has provided it with a pleated synthetic-blend filter media that removes harmful contaminants with ease. The larger-than-usual surface area of the media allows it to withstand longer service intervals.

On top of everything else, this filter is a cinch to remove. The 1-inch nut on top of the canister lets you take off the product with a 1-inch socket. You won’t have to apply any pressure with your bare hands to twist the filter and loosen it from its hiding spot.

Pros

  • 1-year limited warranty
  • Easy wrench-off removal
  • Heavy-duty construction

Cons

  • The nut may leak

Genuine Chrysler Part 5083285AA Oil Filter

Genuine Chrysler Part 5083285AA Oil Filter

Most fuel filters aren’t exactly easy to install. They require hard-to-find tools that aren’t normally included in a car owner’s toolkit – thereby leaving you no choice but to purchase them separately. The Chrysler oil filter is different. You can install this OEM unit with your bare hands.

As easy as it is to install this unit, its removal is doubly easy. Chrysler has provided it with a fluted shell that makes it a cinch to remove this air filter from beneath. You won’t have to spend more than a couple of minutes to dismount this product.

Its heavy-duty construction is equally worthy of our praise. As it allows this model to withstand the extremes of temperature and prevents it from simply buckling under pressure. The sturdiness is one major reason why Chrysler has warrantied this product for a year.

Not everything about this model is hunky-dory though. Some buyers complain that they weren’t able to fit in inside their RAM 3500s. Others report that their filter was delivered with no gasket, which made the unit impossible to use.

Pros

  • Cellulose filter media
  • Fluted shell for easy removal
  • Meets OEM oil filtration requirements

Cons

  • Won’t fit RAM 3500s

Dodge Ram 6.7 Liter Diesel Fuel Filter

Dodge Ram 6.7 Liter Diesel Fuel Filter

Those of you who are wary of testing aftermarket filters might want to check out this OEM replacement filter. Mopar has made it a perfect fit for all Dodge Ram 6.7-liter vehicles. This means that it won’t pose any issue on the compatibility front. 

Everything about this filter’s shell oozes sturdiness and durability. The anti-caustic housing keeps rust and corrosion at bay whereas the leak-resistant sealing components prevent any oil spillage. Such a robust design means you can count on this filter to withstand tough conditions.

Housed inside the filter’s shell is a fuel or water separator. It traps dirt particles and 98% of water-borne contaminants to save the fuel delivery components from any damage. The separator also minimizes restrictions to ensure that clean fuel flows seamlessly into the engine.

The only downside about this filter is its limited compatibility. It’s an OEM fit and won’t fit any vehicles apart from the Dodge RAM ones. Equally off-putting is its astronomical price tag which may serve as a deal-breaker for consumers hoping to get an inexpensive product.

Pros

  • Cellulose filter media
  • Fluted shell for easy removal
  • Meets OEM oil filtration requirements

Cons

  • Won’t fit RAM 3500s

Cummins Filtration FS53000 Fuel Filter

Cummins Filtration FS53000 Fuel Filter

The Cummins Filtration FS53000 fuel filter is designed for Dodge trucks manufactured between 2010 and 2017. It provides an OEM fit for all the 2500 and 3500 models and does not harm their warranty. That means you can install it with total peace of mind.

You can count on this model to do a fine job of filtering the fuel. It has a 2-step microfiltration system that prevents dirt particles from making their way inside the engine with the gas. The filter’s outer layer keeps 5microns contaminants at bay whereas the size of the inner layer is 3microns.

Also on offer is an O-ring. This gasket that is made of a flexible material creates a strong seal between all parts of the filter. It also makes sure that there aren’t any leakages in the filter and keeps it going smoothly. The O-ring also makes the filter’s installation a cinch.

Pros

  • OEM fit
  • 2-step filtration
  • Easy to install

Cons

  • Some users complained of not receiving an O-ring

ATRACYPART - 6.7L Cummins Fuel Filter Water Separator Set

ATRACYPART - 6.7L Cummins Fuel Filter Water Separator Set

Three specific features of this model are the most worthy of our attention. Start with the high-quality replacement filter. It boasts a multi-layer filtration media that can keep out 98 percent of water contaminants while also ensuring a steady flow of fuel to the engine.

Then comes this model’s anti-caustic housing. Most filters you see on the market started showing signs of wear and tear after a few months. This one won’t. Its anti-caustic housing shields the inner walls of the filter from getting scratches from the contaminants inside the fuel.

Equally noteworthy is this model’s long lifespan. Supported by superior sealing components and premium quality materials, this fuel filter – water separator set is capable of lasting for years. Perhaps that’s why it comes with a sizable warranty.

Pros

  • Anti-caustic housing
  • Superior sealing components
  • Multi-layer filtration media

Cons

  • May void vehicle’s warranty

Dodge RAM 6.7 Liter Diesel Fuel Filter Water Separator Set

Mopar - Dodge Ram 6.7 Liter Diesel Fuel Filter Water Separator Set

Here is another fuel filter that doubles as a water separator. It is equipped with a filtration media that not only separates contaminants from the fuel that has made its way inside the engine –to keep the engine running smoothly, but also separates water from the filter.

Installing this filter would be easy if you had the right tools. They include a 28mm socket, universal joint swivel, filter wrench, garden hose and a bucket. All these tools are a part of most homeowners’ kits so it might not be difficult for you to get them from your local hardware store.

You might find it pleasing to note that this model has improved on where the previous fuel water separator set lacked. It meets all the OEM specifications of 6.7L Cummins. That means installing it in your engine won’t void your truck’s warranty.

Pros

  • Won’t void vehicle’s warranty
  • Fits vehicles that are 2013 and newer
  • Can be installed on your own

WIX 33255 Fuel Filter

WIX 33255 Fuel Filter

The Wix 33255 fuel filter came straight from the heavy-duty league. This model is made for vehicles that are driven on tough roads or under dusty conditions. Its external build as well as internal flexibility enable it to withstand the toughest conditions. Here’s how.

Most filters you see on the market have a medium-size filter media. Their performance level nosedives once the incoming dust eclipses a certain level. That won’t be the case with this fuel filter as its 3.766grams filter media can handle more particles than most analogs.

Some of its users complain that this fuel filter is pricier than most. They aren’t wrong. But what they may not realize that this model has the features to justify its asking price. Aside from the aforementioned filter media, such features include its ease of installation, durability and sturdiness.

Pros

  • Comes with an O-ring
  • Fits perfectly and seamlessly
  • Large surface area of filtration media

Cons

  • Costly for a simple fuel filter

On the inside, this model features a filtration media that allows the incoming fuel to flow at up to 90 gallons per hour (5.7 liters per minute). Such flowrate is impossible to achieve for the fuel due to other design constrictions in the engine but it gives tells you all about this model’s efficiency.

Cummins Filtration has equipped this filter with a new water in fuel sensor. This lets this model send readings to your vehicle’s computer – which then uses those readings to automatically adjust other workings inside your engine.

Pros

  • Provides a perfect fit
  • Can be used in older 6.7L Cummins vehicles
  • Has new water in fuel sensor preinstalled

Cons

  • None

Best Fuel Filter for 6.7 Cummins – Buying Guide

Type of fuel filter

Following are the three major types of oil filters:

Spin-On Oil Filter

These filters require you to replace the entire filter, its housing and element when you replace filters. They are much easier to install and remove and don’t cost much as well. The only major problem with these filters is that they aren’t easy to dispose of. Here’s why.

Spin-on oil filters have built-in automotive fluids that disperse as you throw them away. Regulators don’t like this one bit and have therefore made stringent laws on how and where you can discard these filters. That’s the reason why not many people use spin-on oil filters these days.

Pros

  • Easy to install
  • Competitively priced

Cons

  • Difficult to discard properly

Cartridge Oil Filter

While they have been around for almost a century, cartridge oil filters lost the first seat to spin-ons between the 1960s and the 1990s. It happened because the spin-on oil filters were easy to use and replace. But the trend has reversed over the last two decades.

Two events have contributed to their resurgence in popularity. The first is that cartridge filters don’t have any hazardous waste and are therefore better able to abide by strict environmental regulations. Second, the possession of anti-drain-back valves and bypass systems also makes them a better choice.

Pros

  • Environmental friendly
  • Have anti-drain-back valve and bypass systems

Cons

  • Relatively difficult to install

Type of filter media

Here are the major types of filter media used in modern-day filters:

Paper Elements

Filters with a paper element place the semi-permeable material in a perpendicular direction to the direction of the oil. The paper that is used as an element is made of a combination of softwood and hardwood fibers. This allows it to boost a unique combo of flexibility and strength.

The past few decades have seen paper filter elements fall out of popularity. That has happened due to better elements hitting the market, which do a better job of removing particulate matter, rust, and metal particles from the incoming fuel.

Pros

  • Inexpensive
  • Flexible and sturdy

Cons

  • Won’t last long
  • Average filtration at best

Synthetic Fiber Elements

Most filters that you see on the market today have synthetic fiber elements. That is because these elements do an excellent job of removing impurities from fuel. They are also much more durable and therefore don’t require you to replace the filter very often.

These filter elements also have a positive effect on the engine’s performance. As the engine that receives relatively clean fuel not only churns out more power but also lasts longer. This means that synthetic fiber elements give you the best of both worlds.

Pros

  • Last longer
  • Filter impurities better
  • Enhance engine’s performance

Cons

  • None

Installation mechanism

Most fuel filters let you install them in one of these two ways:

  • Wrench-off: As their name implies, these filters require you to use a crescent, socket, or open-end wrench to remove them from the motor.
  • Standard: Such filters have a built-in hexagonal nut that lets you remove the filter using a swivel wrench, oil filter pliers, or a strap wrench.

FAQs and Answers

Q: How often should you change your 6.7 Cummins fuel filter?

A: The answer to this question depends on many factors. Users that fill their engine with high-quality fuel, drive their vehicle in relatively-clean conditions, and keep it in good condition normally get more time out of their fuel filter than those who do the opposite.

Having said that, manufacturers recommend that you change your 6.7 Cummins fuel filter once every two years or every 16,000 miles. That number is a ballpark figure so you may want to consult your vehicle’s manual to get the exact data.

Q: How do I know if my fuel filter needs changing?

A: Here are six signs that you need to replace your fuel filter:

  • Vehicle has difficulty starting
  • Vehicle won’t start altogether
  • Marked drop in engine power
  • Vehicle struggling at low speeds
  • Vehicle suddenly dies while driving
  • Poor gas mileage

Q: What happens if you don’t replace your fuel filter on time?

A: Failure to replace a worn-out fuel filter might expose your engine to numerous problems. Issues like engine misfiring, idling and stalling will become a norm. Your vehicle will face difficulty starting and its check engine light may come off as well.

Provided you choose to ignore these issues lightly, your car’s misbehavior will go one step ahead. It will start losing power during acceleration, as the absence of power from the engine will restrict its output. Finally, your vehicle won’t start altogether.

Conclusion

Most of us rely on our car mechanic’s advice when choosing a new fuel filter. This habit not only prevents us from taking advantage of the best models the market has to offer but it also stops us from getting filters that can deliver a marked increase in our engine’s performance.

Take the abovementioned models as an example. All of them are market leaders in their respective categories and are trusted by thousands of car owners like you. Their installation in your 6.7L Cummins would therefore allow you to enjoy everything they have to offer.
