oil leak f350 7.3 diesel

[harley1974]

found large leak under fuel filter It looks like it's coming from around the Fuel filter canister or somewhere under it. Have any of you had this problem?

Is it an oil leak or diesel leak? I didn't have an oil leak but i had a bad diesel leak around the fuel/water separator housing. if it is a fuel leak i would check and make sure the fuel filter is tight, and see if the fuel is coming out of the drainer valve. The drain on the back has two o-rings that can dry-up and crack. i had a leak out of the drainer and replaced the o-rings for $5. Poof no more fuel leak. If that is the problem and you take it to the dealer they will tell you to replace the entire housing for about $600. Hope this helps.

If it's oil, my bet is it's spewing out of the back of the hpop and you think it's coming from the fuel filter.

Look ALL AROUND the hpop - look for blown Orings...

Maintain are you a diesel technician because i think you know absolutely averything about the powerstroke.

[harley1974]

if it is the hpop what does it take to fix it?

thank you

All it takes is a $30 set of O-Rings a couple of wrenches and about two hours. There is a lot of info on this site about the process. But if you need more guidance I did mine a few months ago and I know Maintain knows how. I'm sure you will get plenty of help around here.

LOL! Definately not, that would be Marc. Most of what I do know has come from these forums. Mostly I try to help others on situations that I've personally encountered. Hpop Orings leaking is one of them

5bucks for either a #5 or #6 (depending upon port) Viton Oring from your local hydraulic shop and some LockTite or the $27.00 kit from Ford. Depending upon which Oring it is will determine how to fix it. Post up when you find the leak.

I sprayed degreaser everywhere and blasted it with water and cleaned it up, then cranked the motor. Remember oil will pretty much fly everywhere but forward while driving after that tidbit of advice it took me 2 minutes to find my leak
Sounds dumb, but that worked well for me.
