Zenoah K331081290 pump gasket G230PU replacement for RC fuel pump sealing  [K331081290]

Pump gasket for G230PU

This gasket is an RC-scale replacement part intended for Zenoah G230PU pump assemblies, supplied without packing. It serves as the sealing element between pump housing faces and helps preserve fuel system integrity in nitro model engines.

Compatibility is indicated by the G230PU designation in the part name, so confirm your pump uses the G230PU pump assembly before ordering. The listing specifies no packing included, so plan to reuse existing packing or source a separate replacement if required.

Installation notes: clean mating surfaces, remove old gasket residue, align the gasket to the pump port openings, and reassemble with even torque to the housing fasteners to avoid distortion. Do not overtighten screws, inspect for leaks during a bench test, and retorque after initial run-in if needed.

Tuning and maintenance role: a sound gasket maintains consistent fuel pressure to the carburettor pump, reducing intermittent delivery issues that can affect engine idling and throttle response, making gasket condition part of routine fuel system checks.
