Return PolicyHolley fuel pressure regulators are designed to precisely control the fuel pressure from the fuel pump to the carburetor. Too much fuel pressure for a given needle and seat assembly can overload the needle and seat and may cause flooding or drivability problems. Each Holley fuel pressure regulator is fully adjustable so regulating the fuel pressure to your engines needs is a simple task. All Holley regulators are pre-set at the factory so there is no guesswork when first installing the regulator. The Holley 12-803BP fuel pressure regulator features 3/8" NPT in/out ports and a 3/8" NPT return port.

I needed a return style regulator for my fuel pump. I wasted time and money by buying a Speedmaster unit. It lasted around 6 month's and started leaking out the top. I had been running a Holley non return style for years with zero problems or complaints. Hopefully, this one will follow suit.
