Fuel Spring

The Fuel Spring from K.S.E. Racing is a precision fuel valve spring designed for use in fuel systems. This component is crucial for managing the operation of bypass return fittings, regulating fuel pressure, and preventing overpressurization during engine operation. It is suitable for racers and performance tuners looking to maintain consistent fuel delivery.

Manufactured from hardened steel, this fuel valve spring offers reliable spring rate consistency and fatigue resistance, ensuring durability across numerous duty cycles. Its compact design measures 1.9 inches in length with a 0.45-inch diameter, allowing for easy integration into existing fuel system assemblies without modification. The steel construction guarantees performance under thermal cycling and high-pressure conditions.

This replacement spring is essential for anyone servicing or upgrading a K.S.E. Racing fuel system. Whether addressing worn components or assembling a new high-flow setup, having genuine springs ensures proper bypass valve function and prevents fuel pressure loss. Each spring is sold individually, making it easy for technicians and racers to replace worn parts as needed.
