This is the passenger-side (right hand) high-pressure fuel rail for the 2011-2016 6.6L Duramax LML, GM part number 12620532, manufactured by Bosch. The rail receives high-pressure fuel from the CP4.2 injection pump and feeds the four injectors on the passenger side of the engine.
Key Features
- GM part number 12620532 (Bosch F00RL00591)
- Passenger side (right hand) rail; the driver side is a separate part
- Feeds four injectors
- Stainless steel
Benefits
When an LML's CP4.2 pump fails, it sends metal debris through the high-pressure system, and that debris settles in the fuel rails. Reinstalling a contaminated rail can damage a new pump and injectors, which is why rails are commonly replaced as part of a CP4 failure repair. A new rail is also the fix for a rail with damaged threads or sealing surfaces.
Fitment
