Product Overview

This mechanical pump transfers diesel fuel from the tank to the injection pump. When it gets weak, the engine may become hard to start, lose prime or struggle to maintain fuel supply under load.

Match 04231021 and compare the flange, drive lever and fuel-line positions to the original pump.

Before replacing it, check the fuel filter, tank pickup and hoses for restrictions or air leaks. Those problems can make a good pump look weak.
