the car is leaking fuel from somewhere forward of the transmission. it seems to be that most of the fuel is leaking from the drivers side but it looks like a little is dripping from somewhere on the passenger side. i have started the car a few times to see where where its coming from but once i see it start to drip i turn it off.
My question is where could i find a diagram or pictures of how the fuel lines are routed. i tried following it from what i thought was the fuel filter (about midway through the chassis perpendicular to the drive shaft). there is also a pair of metal lines that seems to bypass the fuel filter and go straight from the engine to somewhere out back. are those the return lines?
thank you for the help.
