1971 C-10 gas gauge ot working...
I helped a friend locate this 71 C10, around Covid time, March 2022.
It seemed like the gas gauge worked when he got it, but has seldom work for quite a while. I had the sender out of it, recently. This is a California emissions pickup (350), sender has 3/8 and 1/4" pipes on it. I tested the float movement with an ohm meter. That functioned fine. Right after I reinstalled the sender it went to 1/8 tank reading, which was likely correct. Now it just reads a fuzz off the "E" mark. I put $35.00 gas in it a minute ago, gauge did not move.... I'm wondering what the common problem could be with these pickups, if there is one... Gauge cluster is original, old...it is the 6 hole type. ![]() Thanks!!! |

The float itself will fail.

Re: 1971 C-10 gas gauge ot working...
Here is a link to Tbone1964's great troubleshooting guide for fuel guages. The guages are pretty trouble free but they are 50 plus years old so they might just need some love.

Thanks, all.
My next stab at working on his pickup will be in a couple of weeks. Jeff |

An extreme example of what can happen to the 50 plus year old brass fuel sender floats:
