Hi Dave, You may be missing the grounding strap that completes the ground circuit from the metal, that comes from the gas tank, to the metal line that goes to the carbs. There is a rubber hose that prevents the ground circuit from being competed back to the gas gauge. Try temporarily shunting a wire, across the metal gas lines, on either side of the rubber hose near the gas tank. If that is the problem, JC Auto has the ³clip on² ground strap that you are missing which straddles the rubber tube.

The problem is the send unit will not send the message to the gas gauge on the instrument panel that the tank is full. It reads empty regardless of the amount of gas in the tank. This is what I know: The tank sending unit works. I've run a jumper from the line to the tank to the sending unit and as I manually move the float up and down(while grounded) the gas gauge goes up and down. This also tells me that the gas gauge works. With the tank unit installed in the tank I have run jumpers from the tank to the frame and from the flange that holds the unit in the tank to the frame. So I think I've grounded everything. the tank unit still reads empty on the gas gauge. Works the same with or without the jumpers on the tank and the keeper flange or the sending unit. What am I missing, that is besides my sanity? Yes there is gas in the tank. Thanks for your help and your welcome for the laugh Zak -- I am using the free version of SPAMfighter for private users.
