Gas Fumes in Garage Overnight

Hello, Folks,

Our 47 Plymouth has been updated with a 1987 Chevrolet Corvette 350 TPI engine. I appears to be a clean installation, including new fuel tank and lines. It runs great, no problems.

I have noticed gas fumes in the garage after the car has been parked overnight. There are no leaks that I can see, and the fumes seem to be coming from the rear of the vehicle. The gas tank is currently full, but it is the same when the tank is only half-full. The fumes are only noticeable after the car has been sitting in an enclosed space for a few hours.

Any ideas on what may be causing these fumes, and how I can eliminate them? Does the TPI fuel system allow for any sort of venting? If so, could this be the source?

I have attempted to do some research on these fuel systems, but I haven't been able to come up with much. If anyone can provide any links to any online resources, I'll gladly do some more homework!

Thanks in advance for your assistance and support.

Cheers, Ken

Could be leaking past the gas cap. Does it have an evap system on it. If not then that's what's causing the smell. And if it does then the system may have a leak.
