What kind of fuel pump does a Chevy diesel engine use?
Fuel pumps or fuel lift pumps draw fuel from the fuel tank and pump it into the fuel injection system. Fuel pumps must keep fuel flow constant when the engine is running. Chevrolet uses two types of pumps; a conventional mechani- cal/diaphram type and an electric type. The mechanical/diaphram type is found on the 6.2 and 5.7 liter diesel engines.
Where is the pump located on a 6.2 liter diesel engine?
The mechanical/diaphram type is found on the 6.2 and 5.7 liter diesel engines. They are located on the front, lower right side of the block. The 6.2 liter pump is driven by an eccentric lobe on the camshaft through a pushrod. The 5.7 liter pump is driven by a lever off the crankshaft. (Fig. 1-4) The electric pump is used on the 4.3 liter engine.

Fuel filters strain contaminants from the fuel prior to the fuel reaching the injection pump. All diesel engine cars and light trucks have a primary fuel filter. The 6.2 liter diesel engine also has a secondary filter. The primary filter for the 6.2 liter engine is mounted to the cowl. A drain petcock is located on the top and bottom of the filter.
