Will powering the gauges backfeed the system if there are no other fuses in the fuse block? If so, I'd have to get a standalone oil pressure gauge, since the current gauge is a part of a gauge cluster. That's one of those questions that cannot be answered without eye-balling the schematic of the fuse block. Mechanical oil pressure gauges are cheap at FLAPS. Also, it wouldn't hurt to crank the engine over a few turns by hand while you have the oil pressure up.
