Hello everyone, I picked up my first mopar a couple of months ago (68 roadrunner with 440hp motor) and have been working to get it road worthy before car season begins here in the desert. On a long list of to do items is installing a working fuel gauge.
The car came with a new looking stock fuel tank and sending unit. When I look at the current connections, the large line goes to the fuel pump, the small line is capped off on the sending unit and there is nothing connected to the stud.
To connect a fuel gauge, I need 12 volts to the gauge, ground to the gauge, and a wire from the stud on the sending unit to the gauge?
Also when I look on summit, there are about a dozen different ohm ranges to choose from. Which one do I need? I believe the sending units are 10-80ohms? Summit has the following choices:
Which one would guys go with?
Thanks,
Don

- 0 ohms empty, 30 ohms full (46)
- 0 ohms empty, 90 ohms full (90)
- 0 to 280 ohms adjustable (11)
- 10 ohms empty, 180 ohms full (5)
- 10 ohms empty, 184 ohms full (8)
- 16 ohms empty, 158 ohms full (30)
- 240 ohms empty, 33 ohms full (105)
- 240 ohms empty, 33.50 ohms full (2)
- 65 ohms empty, 10 ohms full (1)
- 73 ohms empty, 10 ohms full (41)
- 75 ohms empty, 10 ohms full (31)
- 90 ohms empty, 0 ohms full
