Gas sender Options

[partwerks]

Ran out of gas when the fuel gauge read approximately 1/4 tank. I took out the sender to see if there was rust on the guides but none present and float moved just fine. Is there something else that could have taken a dump and be giving me a false reading or do I just need to get another one?

The sender in my 71 would move top to bottom when the sender is out and turned upside down. But in the car with the slow movement downward, the float would stick. I had to take the sender apart and really polish the center post. Once the post was polished, the gauge has worked correctly.

Also had an issue with the 71's gas tank where the rust in the tank clogged the openings in the fuel pickup bowl (the upside down coffee can inside). With more than about 1/4 or 1/3 tank, fuel to the pickup went through the top of the bowl.

When fuel level dropped below the bowl top, the car started to get starved for gas as the bowl emptied and would stall. Just a little fuel would leak through the clogged epenings, so the car would start and drive if I waited a bit between stalls.
