Just from what I see it looks like where my fuel pre filter bolts on to the block is leaking fuel. Is this a common leak spot or is there somewhere above this that could leak such as a fuel line? Also what are most of the common spots for fuel leaks? When my truck is idling It doesn't seem to leak but as soon as I give it a good couple rev's and climb back under my truck to take a look it leaks like mad and also when I shut my truck off. Any help is greatly appreciated. Every week is another problem

 

I would let it dry and then start the truck and try to find where it is leaking. Give it a rev from under the hood if that speeds things up but be safe...I heard that stuff is flammable You probably just need to replace the o-ring on the housing you'll need something like this:

It's not the pre filter itself leaking, but what I can see is it is the fuel line that comes directly into the top of the pre fuel filter housing. Does anyone know what is required to fix this?

Hoping someone can help me with this but maybe its even my lift pump?

Been doing a bit more of an analysis , it looks as if the #3 o ring on my lift pump is leaking, thats the one behind the primer button. Should I go about replacing this o ring or the pump itself?
