Not quite. I'm having fuel supply issues now. My fuel pressure is set at 40psi, which is overkill right now. It should be about 28-30psi, but that isn't a big deal. The problem is that when I turn on the key pressure is good at 40psi. When I actually start the motor and she starts to drink pressure falls at a steady rate untill the motor dies. This is either a fuel pump not working right for some reason. Or, the regulator is stuck open and all the fuel is dumping back into the gas tank. I used a line lock to close off the return line from the regulator. My fuel pressure jumped up to 55psi, and it ran a little longer, but still eventually died. Fuel pressure fell of at about the same rate, there was just more initial pressure so it ran longer. Has to be the fuel pump, but why would it build pressure at first, then not be able to meet the demand? Strange.
You can see what it does in this video.
