G230PU Pump Gasket for RC Fuel Pump Sealing - Zenoah K331081290  [K331081290]

G230PU pump sealing gasket

This gasket is a replacement RC-scale component made for Zenoah G230PU pump assemblies and is supplied without packing. It seals between the pump housing faces to protect the fuel system in nitro model engines.

Confirm compatibility by checking for the G230PU designation on your pump assembly before ordering. No packing is included with this item, so plan to reuse existing packing or obtain a separate replacement if necessary.

Installation notes: clean mating surfaces thoroughly and remove any old gasket residue, align the gasket with the pump port openings, then reassemble using even torque on the housing fasteners to avoid distortion. Do not overtighten screws; carry out a bench leak check and retorque after an initial run if required.

Tuning and maintenance role: a sound gasket helps maintain steady fuel pressure to the carburettor pump, reducing intermittent delivery that can upset idle and throttle response, so include gasket checks in routine fuel system inspections.
