Ok, some more research lead me to some more info on these rails and a question.
It seems to be that this setup was only on '92 and '93 Magnums, so they could be a little hard to find. Guess it just depends on how many of these trucks are in your area.
I found fuel pressure specs for all the Magnums and they are as follows:
'92&'93- 31psi at idle with vacuum line connected and 39psi at idle with vacuum line disconnected
'94&'95- 39psi
'96&later- 44psi +or- 5psi
Now the question. Since I'm using the regulated rail, but am running the '94-'95 computer/harness, should I just leave the vacuum line off the regulator so I'll have the constant 39psi it calls for?
