Zenoah K285081290 G380PU Pump Seal (no packing)  [K285081290]

Replacement Gasket for G380PU Pump

The K285081290 gasket from Zenoah is made as a direct replacement seal for the G380PU pump assembly and is shipped without any packing. It seals the pump housing to help keep fuel and pressure stable for consistent engine behaviour.

Use this spare part during scheduled pump servicing or after stripping the assembly to restore proper operation. It helps maintain the prime and pressure balance that affect fuel delivery and throttle response on nitro rigs.

Installation notes:

• Clean and inspect the mating faces to remove deposits or scoring before installing the gasket.
• If the pump has been opened or starts to leak, fit a new gasket rather than attempting long-term repairs.
• Fit the gasket flat in the cavity and reassemble parts in their original layout, taking care not to overtighten screws.

This replacement is practical for workshop or field repairs and helps hobbyists eliminate pump leaks, refresh seals, and get engines ready for running sessions.
