'69 Camaro. I replaced a broken sending unit in the gas tank. With 5 gallons of fuel in the tank it reads just over empty. With the tank completely full it reads just over 1/2 full. Can I just move the needle on the gauge or is there another way to get an accurate reading? The wiring is completely new and checks out OK. Thanx in advance for any help.

I would guess you have a problem with the float.You can get a small flashlight and a yard stick and go into the tank from the neck with the key on and lift gently up on the bottom of the float to see if the gauge rises.Two people works better.This will tell you if the float has a problem.

The tan wire from the sending unit to the gauge comes up through a grommet at the rear of the trunk floor and plugs into a connector in the taillight wiring harness. Disconnect this wire from the harness at the connector, and connect a multimeter (on the ohms setting) between the connector on the tan wire and a good ground. As you gently move the float up and down with a yardstick, the multimeter should read "0" ohms when the float is all the way down (empty), and should read 85-90 ohms with the float all the way up (full). If this is not the case, it's time for a new sending unit.
