I have a 69 Stingray w/350c.i 4-speed. I am getting a very bad fuel smell in the cockpit of the car. It is not so bad when the fuel is 1/4 tank or below and very very bad after a fill up or right after the car is started. this car has a brand new fuel tank and all the fuel lines have been replaced. Any suggestions on where to start looking for the cause of this problem? |

First, Welcome to the Forum  If there is no visible fuel leak from the carb down to the fuel pump then I would look for a charcoal canister. I've only worked on (1) '69 so I don't know for sure if it has one but a leak will always leak no matter the fuel level. Vapor smell can change based on the amount of fuel in the tank versus air, which is what your describing and the canister is designed to capture vapors. How long have you owned your car? was there a time it didn't have this smell? when did the smell start? any recent repairs or work done or did this just come out of nowhere? Eric |

I just got the car this past weekend. It did not have the smell when I first drove the car, but it also had very little fuel in it. The car has had a lot of things done to it. The car has been completely restored, an off frame job. It has only been on the road 2K since the build. The fuel tank was one of the many things replaced. Thanks for the feedback. Zar |

Congrats on your new purchase. Chances are it's something rather simple. If it has the canister I'm thinking of it is normally tucked out of the way on the drivers side fender well area down under the master cylinder/power brake booster area. It's looks similar to an old metal coffee can with some hoses connected to the top. Any photos you could post of the engine bay area focusing on the less obvious areas and the fuel lines would be a plus. We'll certainly do everything we can to help you figure it out |

I will look for that. I think I saw something tucked in behind and under the fender. I have seen a canister of some sort thru the vents on the side of the car. I'll post pics as soon as I can. Thanks again I'll look Zar |

I notice a fuel smell in the garage after driving mine. Especially on a warm day or if I have run it hard. Does this make sense? I have been all through the fuel system previously and eliminated the canister. it is plugged at the tank and the cap drilled for vapor. I don't have any fuel leaks but the motor is upgraded and have a Holley 3310. Everything else is normal, in fact it runs like a scalded dog! |

Buster, running it hard and on a hot day could just be some vapor smell your noticing or a slightly over adjusted fuel float level. Next time you come back from a similar run open the hood and pull the air cleaner and look in the venturi area of the carb for wet fuel or any drips from the venturi while the car is running then shut it off and look for any additional fuel leaking down the barrels of the carb. That's the only thing I can think of it there aren't any visible leaks which you indicated there are not. |
