Your first post says the gauge works good, which tells me you removed the sender wire on the gauge and it did not peg.
The wire which was on the pressure sender was removed the gauge still pegs.
This says it is the wire between the gauge and the sender.
Instead of finding the short in the wire, just replace the wire from the gauge to the sender

I assumed the gauge was worked because i unhooked the wire pigtail from the gauge that was pegged and switch it over to the other gauge on the engine that worked and it still pegged.

I have a Livorsi gauge that behaves the same way. After you confirmed the gauge lead to the sender is good and sender ground wire is good, disconnect the sender's wires and check the resistance between your sender terminals. There should be resistance - i.e. not an open circuit. The resistance varies inversely with the pressure but I don't remember the specifics Livorsi provided me.
