Duramax Diesel Fuel Pump Injection Cycle
Duramax Fuel Flow Diagram
Diesel Fuel Tank
Titan Fuel Tanks
This is a aftermarket fuel tank by Titan Fuel Tanks
Fuel is drawn by the fuel injection pump from the fuel tank to the engine through the fuel supply lines.
Duramax Engine
Duramax Engine and Fuel Filter Location
Fuel flows to the fuel filter heater element housing, which combines a water separator, a prime pump, fuel heater element and a filter element.

A mechanical Cp3 fuel injection pump at the front of the engine valley includes the fuel supply pump and the high-pressure pump.
Duramax Cp3 Bag of Parts
.Fuel Injection Parts
The small section of the fuel pump assembly is the supply pump called The Bag of Parts modified by Industrial Injection which creates a vacuum to pull fuel from the fuel tank to the high-pressure pump the vacuum varies with engine load and speed as the engine turners.
Duramax Fuel Injectors
LB7/LLY/LBZ/LMM/LML Duramax Fuel Injectors
The small section of the fuel pump assembly is the supply pump called The Bag of Parts modified by Industrial Injection which creates a vacuum to pull fuel from the fuel tank to the high-pressure pump the vacuum varies with engine load and speed as the engine turners.
The fuel rail pressure sensor is mounted in the end of the right fuel rail. Fuel is used to cool and lubricate the fuel injectors and fuel injection pump. Then the fuel return system is designed to return this fuel to the fuel tank. If the high side fuel pressure becomes excessive, then the fuel rail pressure relief valve releases the fuel into the fuel return system. The return fuel travels through the fuel cooler and then to the titan fuel tank.and does repeating the cycle of Diesel Fuel Injection System
