Description
Overview:
This Spring Delivery Valve is a genuine Yanmar component for diesel fuel injection systems, designed to regulate backflow and maintain correct injection pressure for clean fuel cut-off. Precision-made from durable steel, it helps keep engines starting reliably and running smoothly under load. It is suitable for a wide range of Yanmar industrial engines used in construction and garden machinery, including the L40AE and L60AE. As a direct like-for-like replacement for a worn or sticking valve, it restores consistent fuelling and supports long engine life when used with clean fuel and a well-maintained pump. Manufactured to OEM tolerances, it seats and seals correctly within the injection pump body. Part number: 105546-51330 (Brand: Yanmar; Genuine Part).

Typical Applications:
Used during fuel system maintenance or pump overhaul on small plant and machinery engines powering generators, water pumps, compressors, mixers, compactors, light towers, and agricultural equipment. Ideal for engines that operate for long hours or frequent stop-start cycles, where precise fuel metering and reliable shut-off are essential for performance and emissions control.
Also known as:
Often referred to as an injection pump outlet valve, fuel outlet check valve, pressure-holding valve, return flow check valve, or spill control valve. These terms describe the same function within the injection pump: controlling backflow to stabilise injection pressure and ensure a clean end to injection for consistent combustion.
