is this the same pump as one for the 2005 LLY?
View Staff Answer 

The BOSTECH REMANUFACTURED CP3 PUMP HPP7303 fits the following applications: 2001-2004 GM 6.6L Duramax LB7.

The 2005 is has an LLY motor and this CP3 pump will not fit that application.

Our LLY CP3 pumps can be found here --> Home > GM 2004.5-2005 Duramax 6.6L LLY Parts & Accessories > Fuel System > CP3 Pumps & Upgrades.
