Hello, I have an 86 4x4, 22r truck that i just bought and it has been giving me trouble with the fuel leaking out of the charcoal canister( the upper one). I have replaced it, bought a vented gas cap and it still leaks. I have ran out of ideas and would really appreciate any help you could offer. Thanks.

 

maybe the lines are hooked up wrong? Kev

 

find the vacuum hose diagram for the truck and check that the purge line is connected properly

 

your fuel lines could possibly hooked up wrong, thats what was wrong with mine.
does it run ok...?

 

It actually runs pretty good, just leaks gas. I will check the vacuum diagrams in my chiltons, hopefully i can narrow down the problem...

 

sounds like too much pressure to me then.
but do double check your lines
