YS Engine YSF8062 pump cap DZ175 replacement part  [YSF8062]

Pump cap for DZ175

This is an RC-scale pump cap intended for DZ175 pump units, supplied under the YS Engine part code YSF8062. The component serves as a replacement cap for the pump housing and is used when the original cap is worn, damaged, or removed during routine service.

Installation requires basic workshop steps: access the pump housing, remove the old cap, inspect mating faces and any sealing elements, fit the replacement cap to the DZ175 pump, and verify a leak-free seal during static and running checks. Use appropriate thread engagement and avoid overtightening to prevent thread damage.

Functionally, the pump cap completes the pump chamber and contributes to stable fuel delivery. As a spare part, its role is restorative rather than performance-enhancing, and correct fitment helps maintain consistent pumping behavior during bench testing and field runs.
