The FIE Assy (3TNV70-DPE) is listed at the top level, with the Fuel Feed Pump Assy, Plunger W/Barrel, Delivery Valve Assy, and Control Rack each shown as separate orderable components. Pull part numbers for every item you are replacing and cross-reference the Remarks column for applicable variants.

Open the Cooling Water System list on page 13. The Water Pump Assy, V-Pulley (Water Pump), Gasket (Water Pump), and Cooling Fan are each cataloged with separate part numbers. Add the Gasket (Water Pump) to your order alongside the pump assembly; it is a distinct line item and does not ship included with the pump assy.
Manual Section: Cooling Water SystemStarter motor sub-clutch part number needed, pinion spins freely but won't engage ring gear p. 19
Locate the Starting Motor parts list on page 19. The Clutch Assy, Sub is cataloged as a discrete replaceable component, separate from the full Starter assembly.
