Incorrect Fuel Guage

Incorrect Fuel Guage
Full fuel tank only gets the guage up to about 5/8 reading. Fuel use and guage movement seem to correspond but I've yet to drive the guage needle below the "E" so can't be sure if consumption / guage movement is linear all the way to dry tank. Sending unit? If yes, is there any adjustment involved with new unit or is it as simple as shop manual makes it look? Pony is 69 Fastback, I believe with original tank. Thanks.

where is this tab?

The sending unit has a tab on it which regulates the float movement. If you bend that tab you will see a difference.

RE: Incorrect Fuel Guage
I have the exact problem as Nasty69. I have not replaced the sending unit because I was affraid it might be the constant voltage regulator in the instrument cluster, but I can not get the damn cluster out to check the voltage to the guages. My hands are to big to get to the back of the cluster to unplug all the wires. Is there an easier way to check which is at fault? I am leaning to the regulator being the problem because the temp gauge might show low also. It is at the cold mark but I have a 160 deg thermostat in so it should show a little low. That just seems to low. Any thoughts? Ideas?
