HOW TO: Fix Bouncy/Hummingbird Fuel Gauge Needle

[bluex]

My fuel gauge is stuck on full, any ideas?

Probably a ground issue, mines been doing the same thing. Every once in a while it will jump around but always goes back to full. I haven't had a chance to check it. I use the trip odometer so I know when to fill up

That would most likely be the sensor.

Yep. The one by the exhaust manifold had a destroyed connection for anyone reading through this. The sensor was actually good, just needed to wire in a junk yard connection - I didn't know there was a second temp sensor (technically a temp "switch") until I went to the dealership... Thanks ChrisAU.

Glad to hear it is fixed!

How would I fix that? Is there a YouTube video?

aye, I'm gonna try this here pretty soon. Just got an escalade cluster... anyone know if this works the same with the battery gauge? it twitches a lot more than my fuel gauge, both seem to be generally in the right spots and "work" still. thanks!

how bout buying a new gauge cluster would that solve the problem i got some that works at oreillys and i can get it for like cheap maybe 150 or so

Ya that'd fix it, but that's a $150 fix compared to a $15 fix.

If I wanted to replace the stepper motor for the fuel gauge, does anyone know which one I would need?
Is it this one on Ebay?

I thought I saw a letter designation other than the "C" somewhere.

Figured it out:
F is for Fuel....

$40 is surprisingly expensive

I tried the lube method but it didn't work for me. I ended up buying that exact stepper motor "F" for Fuel. It works like a champ.
