Do you need a lift pump on your LML?

You should strongly consider a lift pump for your LML (2011-2016 Duramax).  Although there are many benefits a lift pump provides, your LML needs them for 2 main reasons, RELIABILITY & PERFORMANCE. 

First, we should clear a few things up before diving into this topic.

• Lift Pump:  A low pressure pump that draws from the fuel tank and pushes it to the high pressure fuel pump.  LML's do not have a lift pump from the factory.  
• CP4.2:  High pressure fuel pump equipped on the LML.  Mounted in the engine bay, directly feeds high pressure to the common rail and draws fuel from the tank. Commonly called the Cp4.
• LML:  Short hand for Chevy and GMC 6.6L, V-8, turbocharged, Duramax engines available in the 2011 - 2016 HD trucks. 
• Brands: DuramaxTuner.com is an Authorized Dealer for FASS.  For purpose of this article we are not going to split hairs over brands.  We certainly suggest doing your research for what is going to meet your needs the best.
