there are two o rings on that valve. they are very easy to change, and them leaking and your changing the fuel filter are coincidence. first pull off the braided cloth hose off the valve, it is stiff, but it will come off without bending the metal portion. the valve is held on by four T25 (if i remember the size right....they may be T 20's) bolts. remove the bolts and replace the o rings in one of two ways. the first way to fix it is to buy the valve kit from ford. it will come with the valve (o-rings already on it) and four new bolts. the other way is to buy just the o rings. they are available off the net, and if i remember right from an earlier post, overloard has a link to them.......but either way, its a relatively easy fix, just dont forget to put the drain hose back on the valve......Marc

Ok when i pulled the old filter out it did not have a o ring on the filter housing ..The only gasket was the one on the top of the housing where the top screws on..I replaced the new filter on with the o ring on the plastic housing....Will that make a difference??????????

the o ring is not visable from inside......it is on the outside of the fuel filter housing, on the back. the valve is black with a yellow lever. the o rings are between the black of the valve and the housing. you did nothing to cause this and couldnt have predicted it happening.......Marc

i guess maybe im not understanding you clearly. the filter your truck has right now should have an o ring on the actual fuel flilter towards the bottom, and another o ring goes at the cap. if the old one did not have one on the filter, your fuel was not being filtered correctly.......but the only o rings that can cause fuel to come out of the metal pipe at the passanger side of the front of the motor are the ones i was discribing, and neither of the ones on the filter should casue a leak at that valve. the two o rings i described above are about a half inch or so in diameter....and they are the sealing for the valve that allows it to "shut" when the hole in the rod isnt in line with the main fuel housing.........if its coming out of the metal pipe at the right front of the motor, trust me, those o rings are leaking and need to be replaced. if its leaking fuel into the valley (and none is coming from the metal pipe) then we have other things to look at..........Marc
