Gas smell when car is running..

when the cars off there is no gas smell or leak of anykind…just came back from mechanics shop…no leacks for gas.

they sugjest its becasue i have no charcole canister on the SR…SG did my swap and pluged the line that goes from the tank to the canister with a bolt…also i have no cat so the exhaust smell is high from that…they said that preasure will build up becasue it has no relase …the gas cap has always hissed when you take it off …but even more so since the SR…just wodering do you guys run the canister on your SR’s??

will the preasure build up to unsafe amounts in the tank ??

thanks…

i doubt that pressure buildup in the tank will be unsafe. im running sr with no canister. yeah the gas cap hisses when i take it off… but no biggie. i dont see how it can really build up that much pressure anyhow. its just filtering evaporated gas from the tank. this is what the fsm says about it :
the carbon canister is filled with active charcoal to absorb evaporated gases produced in the fuel tank. These absorbed gases are then delivered to the intake manifold by manifold vaccum for combustion purposes.

start by smelling around and trying to isolate where the gas smell is coming from… like front/rear, passenger/driver side, etc.

I can smell gas when i drive… sometimes its pretty strong almost a deisel smell? and if i come to a bunch of people they all say “your car smells like gas”,…im thinking its driver side where its coming from…but its really hard to tell :S no leak of anykind lol so its very strange…

I had a problem before there seals on one of my injectors went and it was just stinking like gas/horrible millage. Maybe check that?

I have the same thing running no charcoal canister/cat. Hmm…

im not sure about that but i can tell you for one thing my sr tank hissses like a bitch when i take the cap off.

My SR smelt horridly like fuel when I blew the turbo/manifold gasket and the car was riching out to compensate.

No catylic converter = backfire + gas smell.

as for the charcoal canister … ive not used one and i didnt smell any gas… however if u already have the line then just use a KA canister, i believe its the same.

Hm no leacky injector and gaskets are fine …were done ablut 2 weeks ago lol…i dunno i guess thats just the way it is with no cat/canister… seeling as you guys have th same things…

check the bends right at the fuel sending unit i couldn`t find any leaks in my car when i had it but a could smell gas when the car was running becuase the fuel was passing through and out the hole(crack) it might just need a new fsu

lol new sending until last summer on the car
