Was looking at my fuel tank behind the seat. It appears to be sitting at a slight angle instead of straight up and down on its side. I have my 0 - 30 ohm reading with the fuel sender out of the tank and it is showing a correct reading on the fuel gauge as well, ground wire is clean and solid. When I re installed the sender unit into the tank reading is not correct. Would the tank not sitting perfectly straight cause this kind of a problem? Thanks Hugh
