Hello and thank you for letting me participate.
I have a 1980 Avanti II with a 350 small block and a mechanical fuel pump. I recently had the fuel pump replaced at a local garage.
I have been smelling fuel very strongly ever since. I decided to pull the back seat out and the cover to expose the fuel tank. I thought perhaps I had over filled the tank and it was running out the Overflow.
Turns out that the fuel is coming in through the Overflow in the backseat pocket was full of fuel.
My question is, is it possible to have the fuel lines hooked up in reverse on the fuel pump? Would that cause the problem? The quarter inch fuel line coming off of the what I believe to be overflow on the passenger side that comes up and makes a 90-degree turn. The fuel line is totally rotten. Can't tell where the hoes goes underneath the car without getting under there. Any help would be appreciated
