The water and fuel sensor is known for not working at all in most cases.Ī lot of times like what I did, I’ll show y’all in another video when I do more of an overview of what all I have done to this truck. On a stock Duramax with the stock filter housing, the water and fuel sensor doesn’t really work as well. Basically what that’s going to do is allow you to run down to a two-micron filter, which will get just about any kind of dirt and debris out of the fuel. You can run different filters with different micron ratings. 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. You get a brand new CP3 from Bosch or from another company like Xergy. If you get a remanned, it might be a little less than a thousand dollars.
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. Includes your choice of updated 816 or 7Y-Spoke style pulleyĪpplication: GM 6.In this article you know about the importance of having a lift pump on your 2001 through 2016 Duramax powered 2500 3500 truck.Retains factory safety pressure relief valve.Microprocessor controller for seamless integration.Billet aluminum drive pulley with 6 V-grooves/ribs.New BOSCH Duramax LBZ/LMM CP3 pump assembly with heavy-duty mounting hardware.Dual Fueler kit includes all necessary parts for bolt-on installation.This kit will not produce more fuel pressure than the engine ECU requests it will only increase fuel volume as needed to maintain ECU requested fuel pressure.įor racing applications, this kit provides fuel flow to maintain fuel pressure to 26,000+ psi that is essential for highly modified race engines that are seeking to produce high horsepower. In the event of one pump failing the electronic controller will automatically switch all fuel delivery responsibilities to the remaining operational pump. Both pumps work together, each delivering half the total volume of fuel required. Our PPE belt-driven Bosch CP3 fuel pump kit works in conjunction with the stock fuel system and is controlled by a sophisticated microprocessor module.Īdding our kit to your stock fuel system reduces drive load on the stock CP3 pump, thereby increasing pump reliability. Bolt this kit on and your engine computer will automatically recognize both pumps and continue to deliver the precise amount of fuel your engine computer is requesting.
