There are a few reported issues with these filters. The first is that some of the parts aren’t how they’re supposed to be. Not only are some of the inside filter parts not properly secured, but some of the threading isn’t how it’s supposed to be.
The other issue might be the one that is the most common. Depending on what is sent to you, the filter might not actually fit correctly, which can lead to leaking. This could also cause you to have to take everything apart again so you can take out the filter and inspect it. If it’s faulty, you’ll have to spend even more money trying to buy a new one.
When getting ready to actually buy the fuel filter, there are some things you want to keep in mind. These things will help ensure you choose the right filter and could potentially save you money in the long run. You also want to get the answers to any questions you might have. Both of these things are talked about more below.
The first thing you want to consider is what kind of vehicle you have. Different fuel filters fit different vehicles and they definitely aren’t universal. For example, a Cummins fuel filter isn’t going to fit a small Honda or vice versa. It’s important to know the exact year and model of your vehicle, so you can get the correct filter. If need be, you can always get the same version of the filter that was taken out.
You’ll also want to think about the limitation dates. Just like the majority of products, a fuel filter will only be good for a certain amount of time. With that said, though, not every filter is going to have the same life span. It’s important to find filters that fit your vehicle and see which one has the longest span. It’s better to have a longer-lasting filter than one that needs replacing in just a year or two.
While some people might not care, others find it extremely important to only get certain brands. The main reason is that certain brands are known to do a better job than others. If you want the best of the best, then you’ll want to make sure you narrow down your search to only certain brands. If it’s not a big deal to you, then you can get pretty much anyone you want.
Reading the reviews of the different filters you’re considering can really help make your decision much easier. Most people will write reviews that really get down to specific details, such as any issues they’ve had. By reading the reviews, you might be able to save money and time by not buying a product that has a ton of reported issues. If at all possible, try to find reviews for the same filters across multiple websites to ensure there isn’t any kind of bias.
Since they’re quite a few different types of media to choose from, you want to make sure you get the one that will meet your needs. All of these will have different benefits and drawbacks, so it’s important to find the best one. The common media types are listed below.
- Cellulose- these are made with paper and resin-bound plant material. They are mainly used for particulate removal and not for fine filtration.
- Microglass- these are made from synthetic fibers that are smaller and more uniform than the fibers in cellulose. It’s great for biofuels and usually has quite a long life span.
- Hydrosorb/Hydro glass- These are used for 2 purposes: particulate removal and the absorption of water.
- BioTek High Alcohol- These are mainly used to remove particulates in E85 and B100 fuels.
- Monitor Filters- These are made to specifically detect phase separation in ethanol blends and the presence of water in gasoline.
One final thing to consider is the price. Most fuel filters for a certain vehicle are going to have similar prices, but some are way higher than others. The best way to find the product is to consider what your budget is. Once you do that, you’ll be able to look at filters in that range. Keep in mind, more expensive does not always mean it’s a better product!
With most products, there are some questions that people have. Many of these questions tend to be the same and it’s important to know the answers before you decide which product to buy. With that said, here are some frequently asked questions about fuel filters.
Q: Who makes Mopar diesel fuel filters?
A: Mopar diesel fuel filters are made by Fleetguard. Chances are, if a company you’ve never heard of and hasn’t been proven to sell authentic Mopar or Fleetguard products, then chances are that they aren’t authentic products. While most of these products will still work the way they’re supposed to, many people want the actual products and it can be frustrating getting something different than advertised.
Q: How often should you change your fuel filter in a diesel?
A: For most diesel vehicles, it’s recommended that you change your fuel filter every 10,000 to 25,000 miles. If you aren’t sure, check the owner’s manual. One thing to keep in mind is that this is just the recommendation.
If you wanted to, you could easily replace the filters before you hit that amount of miles and it really depends on how much you drive and how hard you are on your vehicle. In fact, many people choose to replace the fuel filter every time they get other services done, like an oil change.
Q: How do I know if my fuel filter needs changing?
A: The 5 most common signs that your fuel filter needs changing are: difficulty starting, not starting at all, shaky idling, struggling at low speeds and your car dies. Since all of these things could be a result of other issues, it’s always a good idea to get your vehicle checked out by a professional when things are different than normal. This could end up saving you time and money in the long run because you’ll know what it is and there’s less chance of extensive damage being done.
Q: How do I know if my fuel filter is clogged?
A: The main issues that happen from a clogged fuel filter are: engine misfire or hesitation, lack of engine power, and random dying or stalling. As stated above, if your vehicle starts acting differently than it normally does, take it to a professional. They’ll be able to diagnose what’s going on pretty quickly and you can decide from there if it’s something you can work on at home or need them to do for you.
Q: What happens if a fuel filter is not changed?
A: A few things that can happen from not changing your fuel filter are: check engine and dash lights coming on, engine performance issues, and breaking down of internal engine parts. Remember, if the internal parts of your engine start breaking down, there’s a chance it could lead to even more problems and more extensive damage. The best thing to do is change the fuel filter as soon as you know that’s the issue. This should really help keep your truck in the condition it needs to be to run smoothly.
Q: Does changing the fuel filter improve performance?
A: Yes. Your vehicle needs to get clean gas in order to work the way it needs to and a working fuel filter makes that happen. In addition to running smoother and more efficiently, replacing the fuel filter can also make you get better gas mileage. There’s also the chance that the rest of your car parts will run better than they have been, especially the ones that depend on clean fuel.
Q: What are the benefits of changing the fuel filters?
A: Some benefits are: better engine power, longer life for your engine, better engine performance, better gas mileage, fewer fuel emissions, and better protection for other parts of your engine and vehicle. Even if these benefits aren’t something you care about, changing the fuel filter will help ensure that your vehicle is running for a long period of time. This is important because a vehicle isn’t a cheap investment, so you want to make sure it’s working for as long as it can.
Q: How many fuel filters does a 6.7 Cummins have?
A: A 6.7 Cummins has 2 fuel filters. One under the hood and one under the bed of the truck. One thing to keep in mind is that some of these products will only include one of these filters, while others will include them both. The best way to find out is to read the box and see what’s included. Also, most will include the needed equipment, like O-rings and most gaskets.
Q: What are the two types of fuel filters?
A: The 2 types of fuel filters are spin-on and cartridge. The spin-on filters are the most common and are steel canisters with a paper filter inside. The cartridge filters are the older style and have plastic housings that require special tools to get them off. Keep in mind, both of these work best for certain types of vehicles and gas types. They also have their own advantages and disadvantages, so make sure you research before making your final decision.
Q: Can you clean a fuel filter?
A: While you can clean a fuel filter, if it’s one made of paper or nylon, you should just replace it. If it’s metal and not too dirty, you should be able to clean and reuse it. The biggest thing to remember is that you don’t want to use normal water or soap on a filter because it can interfere with the filtration system. If you want to clean it, make sure you use a pressurized carburetor cleaner. Once you do that, tap out any debris then let it dry out completely.
Q: Is there a difference between gas and diesel fuel filters?
A: Yes. Most gas filters are cartridge-shaped, while most diesel filters are shaped like a bowl to help remove water more easily. The packaging should tell you what kind of filter it is and it’s important that you get the right one. One thing to keep in mind is that these can’t really be interchanged. Most of the time, they won’t even fit if they aren’t the right kind of filter.
Q: Do I need a secondary fuel filter?
A: While you don’t necessarily need a secondary fuel filter, it will help your vehicle run smoothly and remove any leftover contaminants that made it past the first filter. If you aren’t sure whether or not it will benefit your vehicle, you should consult a professional and see what they recommend. You could also turn to message boards that have experts and people who have used these kinds of filters for long periods.
Q: What does a bad fuel filter sound like?
A: Bad fuel filters will usually give off sounds like jerking or stuttering. It could also be a sign if your engine starts making sounds that aren’t normal. As we stated before, you want to make sure you get your car looked at any time it starts acting differently than normal. Even if all signs point to a bad fuel filter, there’s always the chance that something else is going on.
After looking at the top 5 best fuel filters for 6.7 Cummins, the buying guide, and FAQ sections, you should be able to have an easier time making your decision. The most important thing is that you find the product that works best for you and makes your vehicle run the way it should.

If it isn’t installed correctly, it’s not going to work the way it needs to and you’ll waste more time because you’ll have to take everything apart again to try and find what went wrong.
