Fuel Pressure Regulator

This may sound like w newb question but I haven't seen anything on this. What's the fuel pressure solenoid for if you don't use stock ECU? I plan on cleaning up my wiring in the engine bay and I was just going to pull it off since obviously I have no use for it and then just connect vac line from manifold to FPR (stock). I remember seeing a vacuum lines diagram and what to remove and such and for "race car" with no emision stuff it had pressure solenoid bypassed. If I do this will it change my fuel pressures? I would think not but just checking.

Yes, you can reroute the hose around the fuel pressure solenoid directly from the intake manifold to the fuel pressure regulator. On the stock ECU, you have to leave it plugged in electrically or it will throw a CEL-- I don't know about yours.
