diesel fuel , dirty filter question.
luckyman:
Here's a question maybe someone here can answer. I have a 7.3 in a f250. The filters are black when I change them. The fuel from the fuel filter bowl has black particles in it when I drain it. A few years back I dropped the tank and cleaned the pick up screens. The pick up screen was clean but the return line has a goofy looking plastic piece with screens. Those screens were packed tight and as full as it couldn't fit any more. There are rubber flaps that let fuel around the pick up and also the return screen if they plug. fuel was by passing the return screens for who know how long. After cleaning and changing filters my filters seemed to be much cleaner when changed.
Question, were is all that black particles coming from. the plastic tank, o rings and rubber lines, filler neck rubber. warn primary pump. It's been a few years since I cleaned the tank and now my filters are looking black once again. :dunno:

Diesel is the dirtiest fuel made, plus whatever crap is in the station takes.

Have you ever rebuilt the fuel bowl?
After years, the rubber o-rings begin to harden and fail, most often leading to fuel drips from the bowl into the V of your block. A lot of times the tiny black particles are pieces of rubber.
The first typically to go is the o-ring for your water/fuel drain lever.
The plastic on your cheaper filters will do this as well. I've had good luck with Baldwin filters, you might give them a look. :twocents:

6.7 in a 2015 Ram. Are the fuel filters pretty easy to change?
