Seafoam=fixed gas gauge


Recommended Posts

OK how to be scared in one easy lesson :)

 

The fuel sender is NOT a sealed unit. It is basically a rheostat with with a float attached to the wiper arm.. Over the years the sender can get a film on it. Also if there is too much sulfur in the fuel (a rare but common way to fill a fuel gauge) it will foul the circuit. The seafoam cleaned the rheostat.

 

Oh and dont worry, the car wont blow up. The tank is sealed and without oxygen the gas wont blow up.

Chevron Techron counteracts the effects of sulfer on sending units too. It didn't "fix" my chevy's faulty unit, but it did change it's behavior a bit. Maybe I need another treatment??
