Fix your fuel leak from filter drain valve

Hey everyone!

Sorry for bringing up an old thread, but I'm having a very erratic fuel leak that might be related to this and would like some help if possible.

I have a 2000 E350 with a 7.3 and every once in a while I will get a leak. Sometimes a small puddle after running it, some times, just a little spot on the ground and sometimes a gusher. I've found that with the gusher it is filling the valley under the turbo, but I cannot get the damned thing to leak when I have the dog box off. I cannot see any signs of a leak anywhere. Just wondering if anyone that has done this repair to the o-rings had the same type of symptoms? I need to fix this soon as fuel is too expensive to let run on the ground.

Thanks in advance for any help!

Thanks for the reply!

I finally got a chance to see the leak as it was actually happening, now to just figure out where at the fuel bowl it's leaking. This thread is very helpful. Thanks guys!
