fuel leaking where it shouldn't
I recently took out my evaporative emissions canister because it was leaking fuel, i let the engine run on idle for a couple of minutes and gas came shooting out of the hose that was meant to be for the fuel vapor,(that definently isn't supposed to happen) the lines are put right, i'm seriously running out of ideas what to do, if i put a new canister the same thing will happen 'cause fuel is coming out where the vapor should be. I changed the fuel pump when i first got the car and i remember i cut a section off the neck of the gas tank and replaced it with one of those hoses that won't corrode from the fumes( the reason i did this was so i could put the tank back in alot easier) I remember there was a metal tube in the portion of the neck that i cut off, i didn't pay any attention to that small metal tube in the neck of the gas tank, do you think that would have anything to do with my problems??

RE: fuel leaking where it shouldn't
If the car has a vapor recovery system, the fuel system in not pressurized on purpose, but it uses a fuel cap that does not allow vapor to escape from the tank. If the EVAP system is not purging properly by allowing gasoline fumes to be sucked back into the engine, the vapor canister will fill up and the fuel vapor will condensate. The pressure in the tank will build, up and depending on how the plumbing is set up, raw fuel will leak out somewhere.

but the canister problem is alreaady eliminated because i took off the hose that sends the vapor into the canister and let the engine run for a while, i think i even drove it around the block, after close inspection fuel was coming out of the vapor hose, so i t isn't the canister as i previously thought, some how fuel is being sent through the vapor line

to tell you the truth you probably don't have to put that hole. your tank has a tube it breathes from located underneath just in front of the tank. there is four lines coming from your tank ... supply, return, vapor recovery, and another breathing apparatus ( don't know what it's called ) but, i'm pretty sure it can suck in air from that line. which is all you need. drive it around for a while then pop the cap. if it doesn't suck in air you won't need to drill your cap. sick
