Got a fuel leak...

I'm hoping somebody out there can help me out before I have to start tearing the top of my motor apart. I've recently developed a fuel leak that I thought was a leaky o-ring in the fuel filter lid but it's actually leaking from the back of the filter housing. There's a hard fuel line that connects to the back of the housing via a short piece of soft hose about two inches long just below the yellow lever that drains the fuel from the bowl (sorry but that's the best I can describe it). The leak seems to be coming from where the rubber hose connects to the housing so I tried putting a clamp on it. No good, still leaks. It doesn't seem to be a high pressure line so it's unlikely that the hose is split right? Has anyone had a leak like this before? If so was it the hose or a part of the housing? I can see the black peice that the hose connesct to but it's pretty tight in there so I can't tell if that's what's leaking or not. If I have to pull the filter housing out how hard is it and what kind of o-rings or seals will I have to replace? Thanks for ANY info anyone can give me before I have to spend another hour in the freezing wind!

thats the fuel bowl drain valve. you can get new o rings from guzzle's website: Replacement O-rings for Ford Diesel Engines

i would get the blue mil spec ones so you dont have to do it anytime soon. you can do it with the bowl still in the truck. there are 4 torx bit screws that hold it in there and there is also instructions on guzzles maintenance page...

It's the o-rings for the drain valve that are leaking on you, it sounds like. As Clay told me when I talked to him last week about this, it may be a good idea to buy the o-rings for the whole fuel bowl.

I'd get the blue ones, as they hold up better (fluorosilicone vs. viton) Riffraff Diesel: Fuel Drain O-rings

For me, it was the two larger o-rings that were leaking. There are four T20 screws on the back that hold them in.

I just flipped the o-rings over for now, and it stopped the leak, but I was 900 miles from home last week. It took me a T20 bit, a 1" long socket extension, and a 1/4" rachet and about 20 minutes to take care of it all. Here's a good guide.

Thanks Mike, I get a lot of questions on how to pull the fuel bowl and HPOP and I think that will be the next writeup in the Maintenance section.

I am always looking for other PSers to volunteer their write-ups so I can post them on the site. Just need LOTS of original pictures.

Hope to see everyone at RRE in July!
