87 325 fuel gauge is intermittent

[CDA]

I'm restoring a 87 325. love this car, fun to drive.
there's some issues with the electric windows, check engine/ coolant lights.
The fuel gauge is intermittent, works for awhile, then goes to empty. Has anyone had this problem. Is there a fix without removing the dash?
Thanks

Remove cluster, there is a hex nut that can be tightened.. usually a loose ground.

How do you remove the instrument cluster?

Thanks

I've done this so many time but I forgot how many screws are on the bottom but there are two up top for the cluster black outer ring and I think a couple of screws under the panel right above the steering column, you have to take the pedals kick panel loose to unscrew thumb nuts, one on each side and then under that is more screws. The cluster has four screws holding it in, two up top and one on each side. Once those are out, you have to wiggle it out, TOP FIRST and then swing it to one side. Its do-able, just have to finaggle it out. In order to get it out all the way, there are plugs on each side, a simple small flat head will help. You have to have small fingers to get them back on though. Enjoy.
