BY-PASS REGULATOR
Street/Strip Carbureted Applications Two Port Adjustable from 4.5 to 9 PSI
Overview
Holley 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.
Features:
- Adjustable fuel regulation from 4-1/2 to 9 psi
- Preset to 7psi
- 3/8” NPT ports (1 in, 1 out, 1 bypass or return)
- Used in systems with a return line back to the fuel tank
- Quieter fuel pump operation
- Designed only for carburetor use
- Polished finish
- Mounting bracket included
