take a roll of paper towels.. get a nice long piece and then roll it up a bit and put it in a line under the fuel inectors. Run the engine for a bit, then pull out the line of paper towel and see if it has any fuel on it. That will tell you if you have bad seals on your injectors.

If it's not from their.. you leak is most likely by the fuel filter. Wipe it down as well and see if you have a leak from one of the lines.. perhaps your fuel hose is frayed at the connection?

Not much else we can do to help you. You'll just have to get in there and find it.

Try using a cigarette lighter as a light source for those tight spots.. that'll find the fuel for you...

^^ remember if the toilet paper burst into flames at any point... you have found your leak... or at least thats what the FSM says.

also could be the lines to your charcoal canister... if you removed you canister

did you use fuel hose clamps? if you used the barbed clamps its easy to crush and fray the hose end and fuel can leak through the clamp.
