Features to Consider When Buying the Best Fuel Filters

1. Quality 

Of course, when you buy a product, you will expect a durable and good quality to improve your engine’s performance. Today, most manufacturers use aluminum to build fuel filters.

The reason they choose this material is because of the corrosion-resistant assets. It is also crucial to make sure that the internal auto parts are well constructed, made from the right stuff, and well built.

2. Size

Do you know that not all filters can fit your vehicles? Each has its dimensions. Also, they feature various shapes. Choosing the right size to match your engine is essential.

To know the best size of a filter for your vehicle, you should check the system manual or the owner’s manual.

3. Cost 

I understand you want a high-quality fuel filter that won’t be broken after purchasing. You don’t need to think that the more expensive one has better quality. What matters is compatibility. Just read the information carefully and set the budget you are willing to pay for one, then you will be fine.

4. Micron level

To give you more information on the particles’ size, take a look below:

  • Salt: 60 microns
  • Dust: 20 microns 
  • Sand: 250 microns 
  • Silt: 44 microns  

I suggest you choose the fuel filter with five or fewer micrometers. The lower rating can help the process of filtering easier, and the quality of your fuel will be better too. As a result, your engine will be protected and last longer.

To check whether your fuel contains any particles, you can get some samples then inspect them. Dirty fuel can reduce the lifespan of your part. Each filter has a date that expires too. Check the limitation of the product before buying.


Either a beginner or a professional, this matter is vital for you. You will want a product that saves you a lot of time to assemble. So check it out before buying. This can save a lot of issues such as looking for other equipment to set up or hire someone to do that, etc.

Hands-on:  How to Replace Car Fuel Filter


1. Is there a difference in fuel filters? 

Nowadays, they are different in terms of design. The modern ones seem to be healthier because they are built to handle the higher pressure in the fuel system.

2. What is the best micron fuel filter? 

The best micron after the pump is 1 – 40. High performing fuel injector companies suggest a 10 micron or better filter

3. How long do fuel filters last? 

Normally, two years. Or you can check by miles. Every 30,000 miles, you have to change your filter. But that is for old models only. The newer one seems to last longer.

4. Can you clean a fuel filter? 

The best way to clean your filter is to replace it.  Unfortunately, most of them can not be cleaned. They are designed to change rather than be cleaned. So you don’t have that many options in this case.

5. Can you normally drive with a bad fuel filter? 

A bad one can be the reason to make the engine stall when you drive. If it is blocked, the fuel can not run through the lines to the engine so that your engine will be starving. Then it can not run properly.
