The FASS Dodge Stock Replacement Feed Pump is the cure for low quality factory lift pumps found on 2003-2004 Dodge Cummins applications. The DRP provides 2.5 times the flow rate as the stock Carter Pump with the reliability of a FASS pump and is a direct replacement for the factory engine mounted fuel pump. A four year warranty is available by simply filling out and sending in the included paperwork. If you are planning on running close to stock power levels and want to keep the proper fuel pressure to the CP3 pump, this is the answer!
