Fuel gauge not working?

[micah202]

Update..... soaked the old parts and tank in vinegar, very effective for rust removal.
A bit of wiggling and twiddling, and the worn actuator seems to work fine.
It's handy to note that the unit can be tested simply by plugging it in. It doesn't need to be grounded, or positioned in the tank.

Ooph, gettin desperate. The actuator arms are totally worn on both gauge senders I have.
Is there a fix for those?

Otherwise,, someone mentioned this gauge unit above,, but no mention of success or otherwise.

Is this the correct Ohm Range? Worth a try @ ~$50 shipped?
0-90 ohms

Is the actuator arm the part that rubs against the copper coil?

Good news on my issue. I was being impatient with the gauge responding after turning the car on. I was able to repair the sending unit by loosening the copper wire from the coil and soldering to the large metal disk located in the picture. Before putting it all back together I tried again and waited longer. This time it started to react, to say I wasn't fist pumping the air alone in my parkade would be a lie.

Sounds good., you got function back., But have you spent the time to check the sender is responding appropriately at different relative tank heights?

I took some time to be leaving the unit plugged in under the car, shifting the actuator arm to different positions, then checking back every once in a while to see what shows on the guage.

I gottah say it worked a lot better once I was looking at the actual fuel guage itself rather than the temperature gauge in the car,. I had a good laugh over that one.

This might sound like a real silly question but after you soaked your sending unit in vinegar how did you make sure all the vinegar was off of it before you put it back in? My fuel sender seems to kinda work and I think the vinegar soak is my best option to start with.

I wouldn't be too worried about a small residual of vinegar. You can take a heat gun to it if you want to make sure it's really dry. I'm sure that's good enough, but if you're really worried you could wash it down with another solvent, or gasoline. Just don't do that while you're smoking.

As in the post above, you can plug in the sender underneath the car and take the opportunity to calibrate it to your gauge.
