Kennybobby, correct me if I am wrong. The sending unit is mounted on the outside bottom of the gas tank and must be removed from the bottom. You lost me when you were talking about making the adjustment to the wheel inside the tank, but your pics appear to be of a sending unit out of the tank. If I put 4L or 1 gallon of gas in the tank, the sending unit has to be mounted to the tank--correct? (Otherwise, the gas will run out of the bottom of the tank.) I'm just a tad confused on the instructions.
BTW, I cannot see the sending unit inside the tank looking thru the fill hole. Yeah, I could take the filler cap assembly off the tank but won't now, because I just filled it on my way home Thursday night.
