FUEL LEAK !!

[Big AL]

Hello everyone.... I hope someone can help me with this problem.... this has happened about three times not consecutive though when driving for a while
when pulling in the Garage there is a small fuel leak by the passenger side about 4 inches inner front tire not much then it stops !.. not a consecutive drip
about few drops but still I'd like to know what it could be ! Could it be Pressure buildup ? I don't know checked fuel lines and they seem to be fine What could it be ??

Here are your potential causes

1. fuel pump itself (doubtful)
2. fuel line coming into the pump
3. fuel line coming out of the pump
4. if there is a filter after the pump, either or both sides

Regardless, not all that hard to figure out, either open the hood and feel around the fuel line/connections until you find a wet spot or slide under it and do the same thing (or maybe do both)

Check the fuel pump itself. There are a couple holes in the housing for diaphragm failures. Your pump could be in the early stages of failure since you said the fuel lines didn't seem to be leaking. Those holes were designed to pump fuel out instead into the pan in case of failure.

Thanks going to check that.

I just remember that I have EFI and the Fuel Pump is in Tank !

That guarantee's a fuel line issue. When you shut it down, you will have to do an inspection as to where it is.

Looks like a vent valve installed on he vapor return line that someone was trying to hide inside the fenderwell.
Someone else do the fuel conversion ? Not the proper way to do this.
