We recently installed a Holley 12-815-1 Fuel Pump in our track car with the recommended 12-704 Pressure Regulator and a return line to the fuel cell. We cannot get more than 2 lbs pressure at the carb. It seems that all the fuel is just recirculating rather than pressurizing the carb inlet,. Help!

After a run of bad luck with Holley regulators and fuel pumps, I only use Aeromotive stuff now.

Okay, so the Holley Tech Line miss-informed me. The 12-704 is not a return line regulator!! I replaced it with a Holley 12-845 and everything seems fine. I did have to change the hose/fittings to make the change, though. Thanks,.
