your posts are not clear, is engine hot or cold, best is HOT, so we can correlate data. 800 RPM hot idle. you have tachometer 4wd, so when hot is the RPM at 800rpm? 0.8 (1k per tick on dial) 1 = 1000 rpm. so 0.8 is normal is it?
what is your altitude, (sealevel or on mountain, would love to know this) im at 500ft right now where are you"? how high.?
this is physics and the FPR is and altitude device too. so matters.
as altitude rises fuel pressures drops. if not the engine floods with fuel. as yours does.
not one number below is correct. the start high and then all are high but I see vacuum works but the numbers are all high.
my guess is the FPR valve parts leak, the seat in the valve is worn out (shock?) and leaks. causing OFF SET high pressure.
or the return line is partially blocked or as the other poster here had the hose crossed.
but you will find out soon, hope its and easy fix. good luck!

Ran fuel pressure test again, this time 42psi just sitting (hot engine or cold, keyon not started?) this???????? this crazy too high, what test is this?
but drops fast to 35, it is a steady 35 at idle and if accelerate slowly stays 34 to 36 psi, if accelerate fast it bogs and jumps to 40psi let off fast it drops to 30 for split second then back to 35, did not pull vacumm again. I ordered new FPR be here in a few days. The one thing I really liked about this track is low miles, 118 something thousand and all parts are OEM. I was running it without air filter when the issue started ( forgot to get one after dry out) but I did put one in so it's new. Hopefully new FPR will fix it. I got from advance Auto so has a warranty it fails again.
