Hector, the problem probably lies with the plug that connects to the sender. If you look at it closely you will see that the cover can come off that plug. Note the postion of all the wire positions and start resoldering the wires to the connectors. There are only like 3 wires, but put towels down, etc. to keep the soldering gun away from raw gas! This is similar to a dead gauge problem my friend had on his '72 108.
Thanks
David
