G230PU Sealing Gasket Upgrade for RC Fuel Pumps - Zenoah K331081290  [K331081290]

Sealing spare for Zenoah G230PU

This part is an RC-scale replacement gasket made for Zenoah G230PU pump assemblies and comes without packing. It provides the seal between the pump housing faces to help protect the fuel delivery system in nitro models.

Verify your pump carries the G230PU marking before ordering to ensure fit. The listing excludes packing, so factor in reusing or replacing packing when planning the repair.

Installation notes: strip old gasket material from mating surfaces, align the new gasket with the pump ports, and tighten the housing bolts evenly to avoid deformation. Do not overtighten; check for leaks on a bench and retorque if necessary after initial running.

Maintenance impact: a properly sealed gasket helps keep fuel pressure consistent to the carburettor pump, which can prevent hesitant running and stabilise throttle response as part of routine maintenance checks.
