Aeromotive afpr question

[92GVR4num65]

Crazy thing here. I bought a used Aeromotive afpr off here and ive got it installed on the oem rail however for some reason the gauge wont work on the unit itself. Here is the troubleshooting I have done.

Took gauge off and swapped it with known working one off diegos 1309...my gauge worked on his car, his (known working) did not work on mine.
Switched ports on the afpr for shiggles...nope
Took it apart to check diaphragm and it looks good with no obvious imperfections. Also used teflon tape on the adjustment screw since i read online this is a common place for leaks.
Afpr dgaf if its hooked up to vac or not...gauge aint movin.
Unscrewed gauge with car running and almost no fuel came out.
Did i mention car runs....so its getting fuel.
Did i also mention car runs full boost (16 psi) to redline so its getting "enough" fuel.
Just kinda confusing to me that and i can set it since i have no idea what its set at.

Anything ive missed other than buying and doing a rebuild on this thing?
Thanks in advance!!

I would check for some kind of crap that got into it from the fuel system. Sounds like the port where your gauge goes is plugged or something...
GL! If you want to buy a known working A-1000, I could sell you mine and I can get a black one instead!

When I had it apart I could see through the guage port so I know thats not clogged. I also blew through it for good measure.

Sub'd. I'm having this exact issue and still haven't figured it out. Keep me informed of the solution and I'll do the same when I figure it out.

Well, there aren't too many options really. If you tried your gauge on another AFPR, and it worked, you know it isn't the gauge, and if you tried a working gauge on your afpr and it didn't work, you know it is the AFPR. The only thing left to settle is where there is a leak/blockage. I am of course assuming you have SOME fuel pressure since the car is running...Sounds like you need to pull it apart and have a really thorough inspection...probably buy the rebuild kit as well.

GL!
