Reply to "Fuel Gage Question"

George, the sender is a sliding contact potentiometer. If it reads continuous with a VOM, that as good as it gets. Over time, the windings wear and eventually break creating an open circuit. There is no 'tuning' possible, beyond carefully bending the 14" long swinging arm inside the tank, or replacing the float if it sinks. There's a second contact on the sender that turns on the red low-fuel warning light at around 1 gallon left.

The OEM sender is no longer available for 71-72 Panteras with the fuel feed out of a banjo fitting at the rear of the tank. The late sender for '73- up Panteras that has an integral fuel-out line has been reproduced and is available from most of the vendors. It bolts into ALL tanks and on yours, it gives a second fuel-out port if you ever decide to add EFI. The OEM lines on early tanks often rust through, or plug the non-cleanable filter-cloth on the end of the stock line.
