Do this simple test first. Start the car let it run for a while and shut off. Disconnect vacuum line to fuel regulator and see if there is fuel coming out of the regulator. Also, check if the regulator holds vacuum. You'll need a vacuum tester.

If the pressure drops quickly (within 10 minutes) to 0, then inspect check valves. The check valves are on the fuel pumps.
