30 Fuel gauge

Recommended Posts

Hi, I’m still trying to get the gas gauge working. Took the float out, seems to operate properly. But the gauge still pegs to full. Seems like a simple system, but still scratching my head. Thanks

Looks like the DeSoto forum stalled at this one. Mars, the float has a small gear on the shaft that turns the variable resistor in the sending unit. You will have to measure the resistance with an ohm meter to see if it changes when it turns. Sounds like the resistor wire in your sending unit may be broken and touching ground. You will need a meter to find out what is going on. Can't fix these things by guessing
