i got my 3 port 4309 malloyr regulator today and it has 4 ports and one return port at the bottom i only have a feed line and a return then the outlet that goes to the carb what do i about the other two is this the right part or am i missing something?

i guess i can use 3/8" pipe plugs to plug the two other holes i dont need?

Yes, thats what I did. I just plugged the other holes.

I cant remember if my AFPR came with some plugs or not.

3/8" npt pipe plugs work fine. You don't technically have 4 ports since one port is the inlet, which leaves 3 ports open. The return is the bottom one. On my car 2 ports go to the double pumper carb and one is for the solenoids.

They have multiple outlet (regulated) ports for either multiple carbs or multiple carb fuel inlets, plus enough for one to go to a fuel pressure gage.

thanks alot guys tommarow im getting enough cash to get the rest of the parts i need to do the swap. Alls i need now is a carb.
