I have the 502-6 Holley on my truck with a stock 5.7, headears, and true duals. I was trying to back off the pressure, and the AFPR stopped adjusting, and the pressure spiked to 60 psi and won't move. Help? Can I rebuild the AFPR? Is there a replacement for it?

Yes, take it apart, thread the adjusting screw back into the spring compression seat.

I think you ran it off the end of the adjusting screw, might now be ****-eyed & unwilling to re-thread together without disassembly
