Review on High-Performance 68436631AA Fuel Filter Water Separator for 2019-2020 Ram 2500 3500 4500 5500 6.7L, 1500 & 2020 Diesel Engine by Matt Kucrud

I have a quick lubrication station and have been using ifjf products for a long time. For some reason they decided to change the design of their filters for 2017-2021 Duramax engines. The mesh filter inside the filter is no longer pushed into the main body and breaks off, causing the filter to stop working properly. (This usually triggers the check engine light due to low fuel pressure.) In my experience, this cost me about $300 because I had to pay my customer to have it repaired at the dealership and I had to pay them to have my filter serviced. DO NOT buy new ifjf filters! The old ones with the blue o-rings were as good or even better than the ac delco, but these new ones suck!
