still having an ongoing problem with my coolant, gas, and oil pressure gauges all reading about a quarter to high, had truck into the shop and they said all gauges and sending units tested out within specs, and the printed circuit looks fine, basically i paid 100 bucks for them to tell me all they can think to do is put a reducer on each gauge to bring them down within spec, but to me it seems there has to be one common source thats causing all the problems, i hav no idea, ive checked everything i can think of!

Elaborate. Do you have the correct cluster and the correct sending units? How do you know the gas gauge reads too high? Have you tried swapping in another cluster?

should b correct sending units because nothing was changed out and it used to work fine, and well, i know the gas gauge is off because it ran out at a 1/4 tank, ..twice, the only thing ive changed somewhat recently was the battery, haven't tried a new cluster, wondering if mabey the printed circuit could be bad even though it looks ok

You've got some unwanted resistance somewhere.
