Hi everyone
Currently I have a 440 with an 871 bds blower with 2-edelbrock 600 carbs with a barry grant sumo pump with 4 port barry grant regulator with guage for 7lbs of fuel. I have made the decision to go with FiTech 2x4 EFI setup and replace the carbs to make the car more user friendly. I can get my hands on a Barry Grant EFI king sumo pump but my question is can I use the same 4 port regulator I have and just change the gauge on it so instead of having a range of 4-12 to something 30-70. or do i just need to buy a new one.

thanks
Frank
