You have a crook Tank vent somewhere. They ofetn get clogged up. Ill loook under mine tomorrow and let you know which one it can be.

thanks alot ive got this bolt screwed in the fume line at the moment so it dosnt piss out where are the vents on the tank?

That is the vent of the tank.

Could be the way your fuel tank has been setup for the 4age. Say if someone has kept the old 4ac lines (if yours is a convert) they would switch the return and the vent around to reduce fuel pressure. Problem being that the old return line pipe feeds right into the tank and the vent line is flush with the top of the tank, therefore when pressure builds up in the tank it forces fuel up the pipe.

Otherwise it could be a vent line restriction (maybe some compressed air to clean it out).

the charcoal in the canister goes hard after years of vapouring. Shake it an see. they cease to hold vapour and thats probably why you have fuel leaking out.

I agree with Nikkojoe. Someone has probably switched the return line and the vent line around by mistake.
