Diesel trucks from the factory typically come with a 7 micron or higher OEM fuel filter that is only about 60% efficient. That’s right, 60% efficient! The injector manufactures for these engines recommend at least 4 micron or better!
This along with increasingly bad fuel, and poorly designed fuel delivery systems on some brands is why they are notorious for taking out the injectors. In fact, OEM injectors are typically on backorder due to so many being sold worldwide. According to an in-depth research study conducted by CAT, the 7 micron particle has been shown to be the main cause of accelerated pump and injector wear in the Common Rails producing upwards of 26,000psi.
These 7 micron particles blasting through your injectors at that kind of pressure result in premature failure which can cost upwards of $3,000-$4,000 in repair bills. CAT fuel filters are made to the highest level of quality in a factory, specifically designed to produce ‘zero tolerance’ filters. CAT built this factory that completely manufactures the filter without a human being touching it, because filter manufacturing can be very tedious and boring, which results in human error.
The results of this factory process are a true, 2 micron fuel filter removing 2 micron and larger particles with over 98% efficiency. Do your own research on these CAT filters. For the money and the nationwide availability, you will be pressed to find a better filter out there.
This past fall, we had an injector fail, and replaced them all. Luckily I work in an industry that I was able to get the replacements at a more reasonable price, it was still an expensive fix.
This week I took the time, and installed the CAT brand 2 micron filters. It was long over due, since these have been sitting on my desk for a few months.
On the road you are forced to buy fuel from many different sources, and I wanted to provide as much protection as possible. Since there isn’t a “premade” kit available for the Excursion, I bought the filter housings and the necessary fittings, and made my own kit.
