unresolved fuel leak

Postby sidewayzsc300 » Wed Aug 03, 2011 6:27 pm

89 240sx KA24E
I have a fuel leak when tank is above 3/4 full. Liquid fuel is pushed through vent line and out vapor canister. I have inspected the vent line and there is no visual damege (kinks,bends) and also replace the fuel check valve thats in the vent line. Still have original gas cap. Is the cap suppose to vent at certain pressure to protect system? Does anyone have any answers and other things i can check.
