Fuel Filter Head - Repair or Replace? - Diesel Place Jan 19, 2014I noticed fuel on top of the fuel filter head, but it was not in a place where it could have come from the bleeder screw. I've surmised that I probably broke one or more seals in the filter head assembly and need to fix the problem. Here are the options as I understand them: 1. Replace with the OEM fuel filter head at a cost of $600 plus labor. 2.
