After both my fuel gauge and temp gauge quit, I replaced the regulator. The temp gauge came alive but the fuel gauge has either worked OK one day, not worked at all ( reading empty )another day or my current reading of full even after I disconnected the wiring at the sender. It would appear that the wiring has grounded out somewhere before the sender but I haven't got a clue where I might search. I have the tach and speedo out for access but can't find any wiring suspects. I'm stuck! Dr. Lucas seems to have me in a hammer lock. Thanks for any assistance.
