I don't expect you to do this. There are a few of us who could do this and have done this. BUT............if you could hook up a clean gas can on the passenger's floor and run the hose thru firewall to the fuel pump inlet, it would sure eliminate a lot of possibilities. It would point to pump or carb.

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
