Maintenance & Replacement:

Installation Tips:

Clean both the pump mounting surface and the engine block thoroughly before installing the new gasket. Remove all traces of old gasket material and ensure surfaces are clean, dry, and free of fuel or oil. Install the gasket dry unless your service manual specifies otherwise. Torque mounting bolts to manufacturer specifications to ensure even compression and a leak-free seal.

Safety Note:

Fuel leaks are a serious safety hazard. A properly sealed fuel feed pump is critical for safe engine operation. Always inspect for leaks after installation and address any fuel seepage immediately.
