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.

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?
YouTube is your friend.

I haven't had to rebuild the bowl. It has leaked past the drain lever before but that was when the filter was dirty. A new filter wipe out to bowl turn key on and work the drain lever a couple times to clear away any contaminates on the oring and has never leaked afterwards. I do suspect oring ware could be some of the contaminates in the fuel.

Diesel is the dirtiest fuel made, plus whatever crap is in the station takes.
Thats what I was kind of thinking. It may be where I buy from.

Ill look into to that. It makes sense. Wouldn't it turn the fuel dark? Fuels is very bright green, just the filter turning black.
No. Keep in mind it is not alot of oil getting by the orings and your fuel system is constantly flowing while running. Over time the filter turns black. It doesn't take alot if oil to turn a white filter black. If your fuel was dark then you'd run out of oil or your engine would die from low oil/oil pressure. Your injectors are fired from very high oil pressure. Low oil = poor or no fuel injection.

Ok I filtered my diesel sample from the bowl to get a look at the brown stuff. It looks to me to be sludge. It ground up between my finger with no effort to where it disappeared. It does contain aluminum slivers so must be injector ware.
Fuel is pressurized and flows from the bowl to the injectors, how does it flow from the injectors, back to the bowl?
Post by: luckyman on November 15, 2018, 04:35:46 PM
Ill add it starts and run very well. I would like to pin point the issue.

The lower injector O-rings separate the fuel from the high pressure oil system in your heads. High pressure oil system fires your injectors and that pressure is a lot higher than your fuel pressure. If the oil is leaking past the O-rings it gets into your diesel fuel and into the bowl from your fuel return.

Some of those 7.3 trucks had fuel tank delamination issues.
:dunno:
Can you explain that a little further?

The liner of the tank degrades and ends up in the fuel filter. Glob-ish gelatin looking crud. No metal though. Just goo.

Thanks.
The tank is black plastic, not metal like earlier models.

You should call northland diesel services in Bellingham. I bet you could get them cleaned, tested and o rings for them there.

Northland knows their injectors.

You will know it’s time to change injectors when it gets cold and difficult to start in the morning without leaving it plugged in overnight.
I'm good then. I just got back from curlew where it was parked for 3 days. 20 degrees out. heated the glow plugs and she popped right off. :tup:
