Reply to "Fuel Sending Unit"

I've pulled several sending units out of Panteras. On later cars, it can be done w/o removing the side window. I generally find that that the reostat in the tank that reads the arm/float movement is compromised after 40+ years. Wilkinson sells replacement sending arm units for a reasonable price. I doubt the issue is the wiring from the sending unit to the gauge. Although, easy enough to check with an ohmmeter.
