Hey guys and gals I don't kniw if any of you had this problem before I have a e99 f350 7.3 I changed out my fuel filter because it was leaking out the drain tube and it fixed it last time now after changing it it is still leaking out and i don't know why has anyone had this issue before?

 

Sounds like you need to replace the o-rings on the drain valve. This is a common leak problem on the stock fuel bowl. Did you drain the bowl when replacing the filter? Sometimes opening and closing the valve reseats the o-rings on the barrel valve and is a temporary fix.

 

Go to dieselorings.com and order you a fuel bowl rebuild kit. Or at least the o rings for the drain valve.
Bob is great to work with, fast shipping, and great prices. Oh, and this will solve your leak

 

If it is leaking out the drain tube I bet you orings are shot.The ULSD does a number on old orings.Look here.You can get the orings from Bob.Great guy with fast shipping.

Thanks a lot guys o rings ordered that's why i love this site great people and quick responsesi

 

If you don't go with an entire fuel bowl rebuild, two #202 viton o-rings work for the valve (which is the culprit 99% of the time).
