Ladies and gents
Can someone tell me if a fuel pressure reading of 37 psi with the vac line connected is high and if so could that cause loss of power ?

Marginally high but would not cause a loss in power I would think.

What does it read with the line unhooked? That’s the only way I can get a steady reading at idle, and is how we are supposed to be setting it.

Unless you need extra fuel, it sounds a little high. The drop when idling is a sign the FPR is working.

This thread might help.

That's within the normal range.
It can be higher if you have a 255 lph or higher fuel pump & the factory stock fuel lines & FPR.
