Feed your Duramax the fuel it needs with an Air Dog Lift Pump System! While CP3’s (Maybe CP4’s) technically do have very small “lift pumps” in them by design, these pumps are not enough to supply enough fuel that is demanded for over stock applications! This is one of the most common modifications for your Diesel out there! Both the Older and 4G style is available for purchase here at Hardway! We have also included the option for a Beans Sump. Every single truck we install a lift pump here at the shop gets one of these. Much easier to install into the truck as well as it is a 100% included everything kit! Talk about a one stop shop!
What GPH do I need for my build?
Any of the above options will do, however they are rated to handle a certain amount of diesel per a rough horsepower estimation. Use this as a guide when choosing your pump. Choosing a pump that is way over rated for your application is OK. Think of it as a “capability” rating.
100 GPH = Stock to 500 HP
150/165 GPH = Stock to 800 HP; This is the most common choice for applications.
200 GPH = 800 HP+
