I have been having problems with my old car.
I tried to do a fuel pressure test on it and had fuel comming out of the top of the pressure regulator. So I replaced the regulator with one from a 1994 Dodge Shadow, from salvage.
My pressure is between 35 and 40 psi when it should be 15 psi.
I removed the return line from the throttle body and ran a line to a gas can but the pressure remains high,still 35 to 40 psi.
What should I do now?

When I get the engine running it dies within a minute. If I give it gas it backfires through the throttle body.

check for bad plugs as you are getting a backfire or a bad wire also check compression.
