Description
Overview:
A fuel lift pump for Yanmar small diesel engines, designed to move diesel from the tank to the injection system at steady low pressure. This replacement unit fits Yanmar 3TNV76 and 3TNV70 engines and several related families. Built with a robust metal body and durable internals suited to off‐highway use, it supports reliable running in compact construction and groundcare machines. The pump helps prevent fuel starvation, aids priming after filter changes, and maintains stable fuel delivery under load.
