YS Engine YSF2058 Pump Gasket for FZ140 DZ175 Engine Pumps  [YSF2058]

Pump gasket for FZ140/DZ175

This RC-scale pump gasket is a straightforward replacement part designed for YS Engine FZ140 and DZ175 engine pump assemblies. It serves as a seal between pump components to help maintain proper fuel flow and prevent leaks in nitro model engines.

The gasket's role is primarily maintenance and tuning support: swap it when inspecting the fuel pump, after repeated disassembly, or if you detect minor seepage during bench testing. Use basic hand tools to access the pump housing and inspect mating surfaces for wear or residue before fitting the gasket to ensure a reliable seal.

Compatibility is limited to the pump assemblies listed in the product name, confirm your engine model before purchase, and treat this as an RC spare part rather than a performance upgrade.
