I have an external fuel pressure gauge and 60lb injectors, how much pressure should it read with only the key on? Thanks.
 
Key on engine off 35-45 psi.
Engine running vacuum hose attached to regulator 30-45 psi
" " detached 40-50 psi

The hold pressure at schrader valve engine off should be 30-40 psi

This is what i have from the board.

Key on engine off, line primed, stock fuel pressure regulator, 40 psi +/- 1 psi. If you have an adjustable regulator, set the pressure static at 43.5 psi.
