Fuel Delivery System

Diesel fuel drawn from the fuel tank by an engine mounted mechanical fuel pump. See Fig. 3  . This pump is driven by an eccentric cam mounted on the camshaft and delivers 5 1/2-6 1/2 psi to the main injection pump. A small screen type filter is located in the fuel tank pick-up.

A larger sealed 11-12 micron fuel filter is located on the rear of the engine between fuel pump and main injection pump. Diesel fuel arrives at the center inlet fitting on the injection pump after leaving the filter. A fuel return line is provided to return any excess fuel to the tank.
