Can someone help me find this malpassi regulator that will drop my efi pump pressure down to 4-5psi? I'm wondering if it has a return line also. I saw a 1:1 on tweakit.net but it doesnt look like it has a return line.

Thanks in advance.

Are you going carb? I would think that the fuel pump wouldn't like pushing against a restrictor to drop it to 5 psi.

You would probably be better off buying a Carb specific fuel pump.

The regulator does not restrict the fuel pump, it bypasses the majority of fuel back to the tank.

Summit Racing and most other suppliers have several brands of this type of regulator available.
