This fuel feed pump is a replacement component for the fuel system of agricultural tractors. It draws fuel from the tank and delivers it to the injection pump at the required pressure. The pump mounts to the engine block and is actuated by a lever that follows the camshaft lobe. A worn pump diaphragm or check valve causes hard starting, low power, or engine stall under load. The manufacturer machines the mounting flange and lever geometry to match the original assembly, so the pump maintains the correct stroke and fuel delivery timing. On installation, ensure the lever aligns with the cam lobe and that the gasket between the pump and the block is replaced.
