I have a 1997 HD PSD, Has anyone Had a problem with the fuel tank switching valve leaking? I've noticed it don't leak when I use the front tank. When I switch to the rear tank I get a small puddle of fuel on the ground under the cab right in front of the tank. I'm not sure if an o-ring on the rear fuel line is bad or the switching valve is cracked.:dunno:

it could be not switching completly and the return builds up pressure thus pushing threw the quick connect fitting
