DZ70 Pump Plate Gasket Replacement Seal - YSG7074 by YS Engine  [YSG7074]

DZ70 pump plate gasket overview

The YS Engine YSG7074 pump plate gasket is an RC-scale spare made for DZ70 engine pump assemblies. It functions as the sealing layer between the pump plate and housing to limit fuel or pressure loss during operation.

Built for simple bench service, the gasket is intended for use whenever the pump assembly is removed for routine maintenance or fault finding. Fitment reference is DZ70 pump assemblies as stated in the part name; visually confirm the gasket matches your pump plate before installation.

Installation notes: remove the pump plate, clean mating surfaces of old gasket residue and contaminants, then align the gasket carefully before refitting the pump plate to prevent misalignment. Tighten fasteners in the engine maker’s recommended pattern and torque where available, and check for leaks at low throttle before a full-run test.

Role in tuning and upkeep: a correct pump gasket helps maintain steady fuel delivery and prevents minor leaks that can upset engine tuning or cause inconsistent performance during runs. Keep spare YSG7074 gaskets for quick field swaps.
