As said from the sending unit forward you are fine. I would run a long jumper wire w alligator clips from the sending unit ground to batt negative & make sure you have a complete circuit.

With the long jumper wire from the batt neg post clip it to the flat metal on the sending unit to make SURE the sending unit has a good ground and that a poor ground is not causing this malfunction then with the sending unit hot lead from the front plugged into the nub on the sending unit raise the float & see what you get on the gas gauge.

will your ballist resistor affect your signal?Are you getting a good chassie ground?

OK--I ran a solid wire from the neg battery terminal to the sending unit---when I touch it to blue wire get full gage deflection, when hooked up to sending unit with blue wire on sending unit terminal, get 1/2 deflection on gage. This is a 3/8" sending unit with a rally gage. I get the same result with 2 different sending units. What am I missing here??????
Do you have an ohm meter? The sender is just a rheostat that is adjusted by the float level. If the float is all the way up, the resistance should be very low, just a few ohms, just like when you short it out with ground wire. Disconnect the sender from the circuit and measure the resistance from the blue wire to frame ground. No voltage should be present or it will mess up your meter. It is unlikely that two senders are bad but it also is not impossible. If you have the original, measure it just for kicks too. Craig
