My car stinks!!!

[parrish5o]

Maybe you guys can help me figure this out. I am getting a gas smell inside my car. It's nothing major just a faint smell of fuel, but it is no doubt there. It really wouldn't bother me but after riding in my car your clothes and even hair kinda smell like gas. Not what you want to smell like when you walk into the club on Friday or Saturday night. My fiancee dosen't even want to take it out on weekends now because of this. This began about two months back. My exhaust has always had rich smell to it but never inside the car. Nothing has been changed with the engine and I have searched for where it might be getting in and found nothing. I have not had it on the dyno or at the track in awhile so I don't know for sure but if there is any loss of power it is so small you can't feel it. I have dumps on my mufflers and that is what everyone wants to blame it on but I have had those for six years and this has just started. Where could this possibly be coming from.

Have you checked your collectors from the manifolds/headers to the exhaust? Does your exhaust have welds that may have broke or split? Those would be my two guesses.

its not a v8 muscle car without the gas smell running through the interior compartment while cruising around town, its just not the same without it.

I agree, the smell of gas is part of a hot rod and in a way I kinda like it. My buddy's 70 Mach1 reeks of gas fumes. But it's the fact that everyone that rides in my car smells like gas when they get out of it. Plus what makes me wonder is that it only recently started doing this. I have checked the collectors and they are nice and tight and there are no breaks in the welds that I can find and there is no sound of an exhaust leak under the hood or under the car.

I have the same problem, it has that raw gas scent.Sometimes i can smell it and sometimes i dont.....weird.I checked all my lines and stuff and cant find where the smell is coming from.I dont see any leaks any where either..

could it be your hatch bushing? mine use to smell real bad of exhaust untill i put a new one on. just my guess. Also, is your h pipe a 2 piece? mine use to leak from the clamp in the middle but i couldnt hear an exhaust leak. just tryin to put some ideas out there.

mine comes from the carb

oh ya i thought this was pretty funny a couple years back, i was a dairy queen just finished eating, had my stock carb on my 85 gt and it was flodding real bad that night, anyway i back out of the yard and there was a kid and his mother about 6 feet in front of my car, the kid starts coughing real hard, his mother was looking at him, he was rubbing his eyes and saying i smell gas, hahahahahahahahaahhahahaa man did i ever laugh. poor kid though.

Since you probably ripped all the emissions stuff out of the car, that is the price you pay.

The carbon canister vents the gas tanks and is one of the first victims of the emissions war...

Charcoal canister plumbing - one 3/8" tube from the bottom of the upper manifold to the rubber hose. Rubber hose connects to one side of the canister solenoid valve. Other side of the solenoid valve connects to one side of the canister. The other side of the canister connects to a rubber hose that connects to a line that goes all the way back to the gas tank. There is an electrical connector coming from the passenger side injector harness near #1 injector that plugs into the canister solenoid valve. It's purpose is to vent the gas tank. The solenoid valve opens at cruse to provide some extra fuel.

It does not weigh but a pound or so and helps richen up the cruse mixture. It draws no HP & keeps the car from smelling like gasoline in a closed garage. So with all these good things and no bad ones, why not hook it up & use it?

Yeah, you are correct. The carbon cannister got stripped back in about 98. As luck would have it thouth I still have it. I will reinstall it and see if that helps the prob.
