Re: Why do i have a fuel line leaking into my chassis rail? (ke20 / ke25)!

the looping wierd thing is probably some kind of condenser - it uses the long tube to convince petrol vapour to condense and drip back to the tank... well that's my guess.
the line going up the bay and venting to the chassis should be going to a charcoal cannister in the engine bay and the cannister should have a drain that goes to the chassis rail.
that's probably the cause of the fuel smell.
go to the wreckers and get the smallest charcoal cannister you can find from an EFI car. there should be two ports on the top and a drain at the bottom. One port is for the vapour line from the tank, the second port goes to the inlet manifold (and only opens up at high vacuum) and the drain goes to the chassis. The reason for using an EFI cannister is that carbi version would have solenoids and vacuum valves and shit to control vapour relaese to the inlet manifold. The EFI versions usually replace that shit with a simple valve in the cannister.
am assuming that the electric pump is self regulating as you dont have a fuel pressure regulator at the engine bay nor a return line from a regulator to the tank
cheers,
charles.
