Has anyone else seen where the in dash oil pressure gauge on a 1936 coupe is exactly 10 psi higher than a mechanical gauge which is on the same T as the oil pressure sender. The sender is new from Thirdgen.

The sender must match the gauge. Early systems were 50 lb, late were 80 lb. Your sender should have the number 50 stamped on the unit.

Sender that are not stamped on the square drive above the block are older 50# which should be correct. A discrepancy of 10# between two gauges is not uncommon.
