excessive pressure blows fuel o ring out

I have a 2001 F 350 with a 7 .3 powerstroke with 470,931 miles on it. I was driving down the road and notice a mist of diesel behind I pulled over to find diesel fuel squirting from the fuel bowl. After closer look I noticed that part of the o-ring was sticking out from between the cap and the bowl basin. The fuel filter has been on for 3 months never had a problem why would I have excessive pressure buildup in the fuel bowl. is it possible that I have a clogged return line would that be possible? if anybody has any ideas I would be very open to entertaining anythoughts comments or suggestions again thank you for reading enjoy your day and remember "Be smart be profitable and master the journey"

I believe you had nothing more than a bad gasket, over tighten of the lid, some of those gaskets are beveled cut and i had problems just keeping them in the grove while changing them. Does this keep happening or just a one time deal, I had to replace all my fuel bowl o-rings, when ford made the rings they weren't meant for ultra low sulfer fuel, so the coatings come off the o-rings. It started with the bowl drain then the lid, then after researching I realized I had to replace them all. diesel site offer's the complete bowl kit, every oring and then some. comes with detailed instructions as well, and not expensive at all. I only have 250,000 on my 99 but most of that was before the ULS fuel came out. The newer trucks already have the proper orings in them for that fuel, so I changed all the orings out cause I was not going to be adding an additive every fill up. Good luck

Oh man! I had that happen a couple of years ago, my truck stunk for months, lots of running around with the windows down and a/c full blast. Hope yours isn't that bad.

for re assurance, remove the FPR.(on side of bowl, where return line connects to) and check the spring for damage and blow air through line

It's a gasket issue, not a fuel pressure issue. I had a problem with a loose poppet and the retainer in my FPR a while back. I have a fuel pressure gauge and could watch the pressure spike so high that the fuel pump shut off.

This was bad of course because the fuel pump would constantly cycle on and off every second the truck was running. Pressure would spike and the pump went off. As soon as pressure dropped back to within spec, pump kicked back on again. Pretty hard on the fuel pump, but it never caused a leak and I believe it was up near 100 psi.

Just food for thought, several years back i bought an aftermarket fuel filter that was the filter and cap as one molded piece. I started having fuel leaks and couldnt figure out where. I changed the drain valve and that didnt fix it. I finally brought it to ford and they mentioned that the aftermarket one piece filter/cap did not fit right. Charged me a new cap and filter and sent me on my way. Havent had a leak since. Just another something to think about.....
