2 Stage Diaphragm Bypass Valve
QUICK FUEL | Part# Q-F-30-899
High performance diaphragm bypass responds much quicker and maintains the desired pressure setting with greater accuracy than a "poppet-style" bypass. Made of billet aluminum and premium-quality diaphragm and spring materials. For high-pressure mechanical or electric pumps use #17021, for belt drive pumps on alcohol or gas use #17020 (with internal jet). These bypasses can be serviced in the field using #171025 rebuild kit.
