It started working on its own?

My B-body fuel gage has been out for last 3 years at least. Yes, its been a lower priority. But got some of the engine bay work done. And nothing that has anything to do with fuel, and/or fuel tank. I ran car out of gas in my driveway. I pushed it into garage. Put in 1 gal from can. Then drove to station and put in 3/4 tank.

The fuel gage started working. And it appears to be accurate. I have a new fuel sending unit. And was going to replace, but today? I cannot get to fail.

WTF?
 
Cracked float. No fuel so it drained and then floated again when you got gas will sink again in time. Hope I'm wrong ...

I think you might be right. Does explain. Especially if fails again.
 
Use the new float from your replacement sender and reuse the original sender if you want it to be accurate. I did the same thing.
 
Ok. I went out driving alittle harder than normal. I was out on the interstate and ran into a Challenger 6.4 scat pact on the freeway. So of course we did a punch. I flapped it down to 3rd. Up to about 90. Then into 4th. He jumped out to about a car maybe 1 1/2 Length lead. Then I started to reel him back a bit before we saw traffic about 1/4 mile ahead. We stopped our nonsense.

We pulled into a station. And he came out smiling ear to ear. I thought he was going to boast of his better performance. But no. He right away said. "Your old girl was hauling ***!" Expecting me to be far back. I explained with the 3.54:1 Dana rear and 28" rear tire? She is a highway star! But at a dead stop race she would really stand no chance. He smiled and said. "We weren't at a dead stop."
We exchanged # and I think I made a new friend.

P.S. fuel gauge still working. And it reflected 1/4 tank loss from my little highway excursion. Lol.

I love this car. More than any other. The more I rub? The more love it gives. I've had SO many others that were opposite. You rub something? And two more things bleed.

My 69 Coronet gas gauge is hit or miss on working until this summer its worked perfectly all summer, the only thing I've done is left the battery hooked up where typically I remove the battery ground cable when I'm done driving it as I do with all my old cars.
 
My fuel gauge in my 68 convertible is only correct either when full or empty! Every other reading is just a suggestion!!
 
My Plymouth worked and then didn't work.
All I did was loosen up the nuts on the gauge studs enough to wiggle the wires back and forth, tightened them back up and it works perfectly.
Maybe this one belongs in the easy fix thread?

Perhaps. But so far gauge is working as should. I would think a cracked float would fill up then sink faster than it drained on empty tank. But could be wrong. It's possible the float got stuck, and a completely drained tank unstuck?

But I do know. Trying to fix something that is working is much tougher. Lol.

I say leave it alone, unless it stops working again.
 
The sender is a rheostat with a wiper arm than 'wipes' over the rheostat winding [ of resistance wire ]. Both the arm connection, winding, & arm pivot can wear. Remove the sender & check. Arm may need to be bent slightly for consistent contact. Bend just enough to make contact. Excessive force here will cause premature wear.
 
Been over a week. And gauge is still working as should. I was expecting it fill and sink back to showing empty. But gauge is showing very accurate to what I believe is fuel level.

I've learned it's really tough to fix something that is working. Lol. So on to the next maintenance project. And that's to replace a 30 year old 750 vac secondaries Holley carb with manual choke to a new 700 mech secondaries double pumper with electric choke. I'm looking for alittle faster Throttle response and of course a more stable choke for starting and warm up.
