Fuel smell in cabin ONLY when tank is full

[rjd2]

just wanted to follow up and say that it was in fact the cap for the sending unit hole; because of the orientation of the hoses in the new GM style fuel pump, it's hard to get access to the cap(the most ergonomic installation has them lying directly over the cap). I didnt have it fully secured. tightened it down, checked it and its "fuel tight". that tip of slamming on the brakes and then getting out was gold! thanks ya'll!

This forum is the sum total of years of experience by many owners. We have seen it all, it is rare that there is a problem someone never had and a way to figure out and fix it. The hardest ones are when the car has been modified and we don't know all of the details. Electrical problems can be difficult because most owners do not understand electrical systems and if there is a ground problem backfeeds can cause unusual symptoms.
