258 w/Mopar MPI cranks, but not running

[Lumpy Grits]

When the reading was taken.
Was that at idle? Or just 'ign' on and pump run'n??

IIRC, if the vacuum line is disconnected from the regulator at the start of the rail it should read 49lbs +/-

Without vacuum it should be about 40 psi 50 PSI would be too high. If it wasnt flooding outside. I'd take a reading and post it.

I just double-checked and the fuel pressure is indeed 50psi at idle.

I have a vac gauge. Where should I check the vacuum?
If I measure no vac, where to then?

Thanks guys
