Erratic oil pressure and fuel quantity gauges
I pulled the instrument cluster partially out of the dash when I had the truck apart for a bare metal repaint ( Build Threads section). After putting the cluster back in, I've noted the oil pressure and fuel gauges reading low and wandering up and down. (I think engine temperature is working OK). Anyone know of a common problem and a probable place to look...a ground issue, perhaps? Is there a voltage stabilizer in the system? The truck is an '81. Thanks
