Standalone oil supply

[g40 jp]

I fitted a standalone system last year with a fuel pressure gauge, i have just recieved a few gauges one being a oil pressure gauge. could I change this for the fuel pressure gauge or will it not read? ones in lbs and the new oil pressure is in psi. id like to keep them all the same rather than a different colour/make standing out.

Depends what pressure it goes up to and what pressure the standalone operated from i guess?

And you might not get an accurate reading as there setup for different system pressures.
