    My uncle has been getting a fuel smell from the fuel filler area since we changed the fuel pump. So far I have changed the gas cap and the evap valve at the fuel tank. He did have a check engine light that pointed to the evap valve so thats why we changed it with an AC Delco one. I really dont want to drop this tank again but its looking like im going to have to. Unless someone has an Idea on how to smoke test the system? Or is there some sort of metal coupling between the filler tubes? I cannot remember.
