Features to Consider for Best Duramax Fuel Filter

Now that you have the options in hand, it is time for you to check their specifications and details to decide the one for you. But what are the things that you should look for in fuel filters? If you are not a professional in this matter but want to buy the fuel filter for your

Product Micron Rating Filtration Efficiency Maintenance
Caterpillar 1R-0750 Fuel Filter Multipack2 99.9% Less
GM Genuine Parts TP3018 Fuel Filter Kit 4 99% Less
6.6 Duramax Diesel Fuel Filter with Seals 5 98% Less
ACDelco TP1015 Professional Fuel Filter with Seals 5 98% Less
WIX Filters – 33960 Heavy Duty Spin-On Fuel Water Separator7 97% Average

Duramax all by yourself, then considers these below features. The features of consideration are:

Fitting of the Filter

If the filter doesn’t fit in your Duramax, then it is of no use. You cannot count on making adjustments within the engine chamber to fit any filter in it. It might distort the functionality of other parts within the engine.

Therefore, check the specifications of your Duramax engine and match them with the filter compatibility. You can prefer to go for options that have a wider scope of system usability.

Micron Rating

The micron rating is what gives an insight into the filtration potential of a fuel filter. In fact, the micron rating resembles the opening sizes of these filters. The lower the micron rating, the better will be the filtration efficiency.

Hand holding a fuel filter

Some filters range from a 2-micron rating to a 7 or 8-micron rating. The lower ones are the better picks. So, depending upon your pocket limit, go for the one that ranges between 2 to 5-micron ratings.

Sealing of the Gasket

One of the most common defects that the majority of the fuel filters have is a loose gasket seal. The O-rings at times fail, which can result in open orifices, that might lead to leakage problems. Therefore, you need to ensure that the seals within those filters are durable.

And for that, you can check the specifications and reviews of existing buyers to get an idea of the same.

Filtering Media

The higher the capacity of filtering media, the better will be the efficiency. Higher capacity resembles the presence of layered materials for better capturing of the particulates. So, you need to check the efficiency rating of the filtering media mentioned within the specifications to make a decision.

You can choose from micro-glass, cellulose, hydrosorb, and monitor filters. The difference in filters will enhance or deteriorate their filtering potential. The hydrosorb filtering media is for detecting both water and particulates from the fuel composition. It monitors filters for detecting phase separation in water & ethanol composition in the gasoline.


Consider all the important factors and keep shortlisting from these five options until you decide the one best for you. Duramax vehicles are very much robust and powerful. Therefore, they demand uninterrupted power. And for that, the fuel filter must maintain a smooth flow and high delivery rate.

In fact, all the options above have no restrictions on fuel flow to the engine’s combustion chamber. So, you can be sure about no power hick-ups on installing any of these fuel filters in your Duramax. Do your research, choose the one, and place your order!
