Question about 1966 Ford Mustang
Replaced fuel tank and fuel tank gas gauge sending unit. Unplugged wire to tank unit and grounded, dash gauge goes to full and empty. All other instruments and gauges work as well as dash lights. Current to tank unit flashes intermittent when checked with test light should current be pulsing or steady ? Suggest a fix or how to further test. I thank the new tank unit is bad but not sure.
Hi, sounds like you have checked everything properly and you have a bad tank sender, current when checked with test lamp should pulsate.I suggest replace fuel tank sender.

I had a similar problem. In my 1966 Mustang gas tank, the fuel pick-up was on a "float." My float developed a hole, filled with gasoline, and sank to the bottom of the tank, therefore, the gauge always read empty, but the car ran well. All the other gauges of course worked correctly. The repair was a relatively simple soldering job (after removing the float from the tank), but if that is indeed the problem, ensure all the gasoline is drained from the float before beginning the soldering job.
