Many gauges have adjustments on the back and you can compensate if the reading is off. bulent Steve - Make sure you do this (hot water test) while the sender and gauge are attached in the plane. If there is a "ground loop" problem (i.e. significant difference in resistance between sender to ground and gauge to ground) you might be getting an error that way too. If you test them out of the plane they may check out OK but in the plane they may have this additional error. Just a thot!
