Depends on the pump your using. I always match the regulator to the pump. JMHO. Eric L

I don't know if that Holley bypass reg would like the pressure from an EFI pump. I'd look at the Aeromotive 13204. It's specifically designed to knock big EFI pressures down into carb'd territory. It's not cheap, but nothing that's going to do what you want it to do is going to be IMO.

This is the one I use. Works perfect and has been perfectly reliable.

It is not about the pump potential pressure capabilities. The regulator determines the pressure. You just have to make sure the regulator can handle whatever volume your pump and fuel line deliver. No resistance to flow. No pressure.

^^^True statement and bad choice of words on my part. Thanks for the clarification.

OP.....let me rephrase: I'm not sure the Holley regulator, which I belive is designed to work with a lower volume pump designed for a carburerated system, would be able to handle the volume of fuel that your factory EFI pump can provide. But of course, I could be wrong. The regulator I recommended is the one I'm using with my high volume (A1000) pump.
