    Default Holley 12-803BP

    Hello all. I'm pulling my Holley Sniper off and going back to a carb until I get some things sorted out. My question is: Will the Holley 12-803BP Bypass Regulator reduce pressure from the fuel pump that was used for the Sniper, which put out 60 psi. I need it regulated down to 7 psi. I do have a return to the fuel tank. Thanks, Larry

    I used a modified Holley regulator to produce a bypass regulator, which you can buy now as the 803BP, and an EFI fuel pump.
    Carb was Holley 750DP, pressure was set at 6 psi. Gary
