    Hello:
    The last few times I've driven the Stang, I've noticed the smell of gas at a moderate strength located around the left Front (if standing in front of the car) of the engine bay :noes: . I had a fuel pressure gauge mounted inside the bay but disconnected that thinking it was leaking. No go. My thinking is, could the smog pump, or cold air tube be emitting gas fumes? My car does run richer than factory, especially if I drive it, shut it down then restart it again. I checked all hoses to the engine and back to the the Firewall and none show any signs of leaking. Maybe a leaking intake manifold? :dunno:

    Any ideas, or has anyone experienced this too?

    Thanks,

    Potentially a bad fuel injector o-ring. I would inspect all of them VERY carefully.

    New o-rings and pintle caps can be had at NAPA for minimal cost. Replace all of them if one is leaking.

    If your car is running very rich, you could have an exhaust leak. and that COULD be it.

    Hi
    I noticed on my 95GT 5.0 a smell of petrol and it drove me nuts, but found the vacuum hoses had come adrift from the fuel vapour cannister under the left hand fender when standing at the front of the car looking into the engine bay, I fitted new hoses and now all sweet and no petrol smell. Hope it helps

    Yeah?? That's basically where I smell it. Is the cannister that "can" looking item mounted between two hoses and you can see the cotton filter in it? It's just above the smog pump.... O0

    The Canister is under the passenger side fender, cant see it till u remove the plastic inner gaurd and look up towards the antenna base
     
  9. If you top your car off when you fill it up you can get fuel in that vapor canister. Which would explain the gasoline smell, its only supposed to have vapors in it, not raw fuel.

    It's literally inside the passenger side front fender. You have to remove the wheel and the splash guard, and you'll see it just forward of the passenger door hinges. You can't miss it - it's a big plastic black box thingy.

    Ok, cool. That is where I smell it the most. I thought I was running soo rich that gas was accumulating in the cold air tube. I'll check it and I appreciate the info!

    I guess check the vac hoses and reconnect/repair if leaking.

    Most likely perished hoses or the rubber joiners for the plastic tubes :pimp2:, I dont think there is anything you can do with the canister itself. O0

    If you really want it out of the heat, put it under your passenger seat. It's much less work and lives a comfortable life there. That's where I put mine - works dandy.

    I was worried about extending the wires that far
