Using thread sealant on electrical senders could cause added resistance to ground which will make the gauges read lower than actual. Loctite makes an anti-seize called Graphite 50 that is electrically conductive. If you feel the temperature or oil pressure sender needs to be sealed, Loctite Graphite 50 would be an ideal choice of sealant since it will not add resistance to the sender ground.
