A lift pump cleans the fuelĪnother great thing about adding a lift pump is that it cleans the fuel. All it has to do is just pressurize the fuel going into your fuel rails, which then lead to your injectors. We’re adding a lift pump, which will save your injection pump so that it doesn’t have to sit there and pull the fuel through a vacuum from the tank to itself, and then pressurize the system at the same time. Stock form without a lift pump, your CP3, CP4 injection pump pulls the fuel through a vacuum basically and then has to pressurize the system at the same time. So lift pump will help save your CP3 pumps and your CP4 pumps from basically going to shit. You’re looking more towards a thousand plus.

Putting, swapping in a CP3, or putting in a CP3 alone can cost well over a thousand dollars, depending on what CP3 you get. These fuel systems are not cheap in these trucks. It will save your CP3 or in cases with the LML, if you’re still stuck with a CP4, it will help help save that CP4 from cavitation and ruining a $10,000 fuel system. So adding a lift pump is very crucial to the performance of your truck. All Duramaxes from 2001 through 2016, does not have any kind of a fuel pump. What a lift pump does is it takes fuel… It draws the fuel from your gas tank, from your fuel tank and pushes it to your injection pump.
