• FAQ :  Why do I need to install an Aftermarket Lift Pump on my Duramax diesel engine? If you want to increase the performance or power level of your Duramax diesel engine you will need to ensure you obtain the proper flow of purified diesel fuel. Today is very simple to just add aftermarket performance parts to obtain more power. One of the primary principles to obtain increased power is the ability to provide more fuel at the proper pressure and delivery rates. This is where the PureFlow AirDog-II 4G Series Lift Pump comes in. The diesel engine holds the top spot for the most efficient internal combustion over all other engine types, adding a new diesel fuel pump to your diesel engine can vastly increase its performance output level. What does the PureFlow AirDog II-4G Pump do? The AirDog® II draws fuel from the fuel tank, removing water, particulates, and air/vapor. The fuel supplied to the CP3 Injection Pump is now purified and pressurized with a regulated flow based upon the demand placed upon your Duramax engine.
