Bosch F00RL00129 is the new left bank (driver side) high-pressure fuel rail for the 2006 to 2010 GM 6.6L Duramax, the LBZ (2006 to 2007) and the LMM (2007.5 to 2010). It replaces GM 97361353 and ACDelco 217-2433. It fits Chevrolet Silverado and GMC Sierra 2500HD and 3500 trucks, and the Chevrolet Express and GMC Savana vans with the 6.6L diesel.
Shops replace a rail when it leaks at a fitting or when the fuel system has been contaminated, so debris does not reach new injectors. The right bank rail for the same engines, the one that carries the rail pressure sensor, is Bosch F00RL00143. The 2004.5 to 2005 LLY rails (F00R001505 and F00R001512) and the 2011 to 2016 LML rails (F00RL01027 and F00RL00591) are different parts and do not interchange with this one.
Confirm Fitment Before You Order
This rail is for 2006 to 2010 LBZ and LMM engines only, left bank. A 2006 truck can still carry the late LLY engine code, and GM’s catalog lists some 2010 Express and Savana vans under the 2011 to 2016 rails as well. Send us the VIN and the number off your old rail (F 00R L00 129 or GM 97361353) before you order. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Frequently Asked Questions
Which side of the engine does the F00RL00129 fit?
It is the left bank rail, the driver side on these trucks. The right bank (passenger side) rail for the same engines is Bosch F00RL00143.
Will it fit my 2005 LLY or my 2011 LML Duramax?
No. It covers the 2006 to 2010 LBZ and LMM only. The 2004.5 to 2005 LLY takes Bosch F00R001505 on the left side and the 2011 to 2016 LML takes F00RL01027.
What numbers does it replace?
GM 97361353, ACDelco 217-2433 and the GM / Isuzu number 8973613535. The rail itself is marked F 00R L00 129.
Is it new, and do I send my old rail back?
It is a new Bosch rail, not remanufactured, so there is no core to send back. If you are not sure it matches your engine, call 530-668-0818 with the VIN.
