Truck stinks like gas - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Every time I pull into the garage the truck stinks like gas. I was thinking that hooking the evap canister back up might help. Now I have an Edelbrock carb and intake. There is still the line running from the canister to the gas tank but thats all. I could hook one up to the pcv but not to the carb like there was originally. Would that help any or is there any more I could run with what I have now to help any?

Have you check for a fuel leak? If there is no leak then I'd say you should attempt to hook the evap back up. I"m pretty sure it was designed to catch all of the gas fumes and keep them from stinking up your truck.

Might want to make sure the fuel pump is not leaking. The have a small weep hole like a water pump and will leak when they start to go bad. You will never know it because they only leak when running and the fuel will evaporate but you can still smell the gas. The odor will be kind of strong when the truck is running

yeah, like flip66 said. I had same problem and thought like you did with the evap. canister. Turned out after a while the fuel pump leak was bad enough that you could actually see it.

Mine does the same thing and I have everything hooked up and no leaks. I've never really worried about it too much but maybe I should?

Sounds like time for me to get a new fuel pump as well. Time for a Carter

I'm voting on rusted fuel line.

I might have the solution. Mine does the same thing, and I have an Edelbrock 1904 Q-Jet. My well plugs were leaking. They were letting the fuel drain from the carb into the motor, and was causing the fumes. Just something to think about if there are no other leaks.

I found my well plugs were leaking, because every morning when I start my truck, or everytime I start it after it's been sitting for long periods of time, it fires right up, but then dies, or wants to die, until the fuel can get pumped back into it. No leaks in fuel pump or lines. Mechanic said the well plugs were leaking. Put J.B. weld on them, and bam...problem solved and no more fumes. Just something to think about...
