This pressure relief valve is the ideal bypass valve for use with a positive displacement fuel pump (typically not required for diaphragm type pumps). For use with any carbureted race engine using a belt drive fuel pump. This bypass valve is well suited for alcohol carburetors with gear type pumps.
Adjustable diaphragm lets you set fuel pressure while the Holley jet inside allows you to reduce idle fuel pressure without affecting operating pressure. Due to fuel pump variations, the jet is not included. The fuel pump relief valve features a stainless steel seat and bronze popitt valve for maximum resistance to corrosion.
- Easily mounts directly to the carb fuel log
- Adjusting screw on top sets high RPM fuel pressure
- Easy pressure adjustments at 7-14 PSI
- Adjustable to vastly different fuel pumps
- Maximum fuel availability at the carb
- 3/8" NPT ports

We use this on the end of our fuel log. The best thing about it is the jet. It's a copy of a Holley but does the job. Easy to adjust idle and wide open pressure. A must have if you run a belt drive pump.
