2004.5-2005 Chevy/GMC 6.6L Duramax LLY Right (Passenger) Fuel Rail with Sensor | Bosch F00R001512 New
Bosch F00R001512 is the new right bank (passenger side) high-pressure fuel rail for the 2004.5-2005 GM 6.6L Duramax LLY (VIN code 2). It replaces GM 97303658. It fits Chevrolet Silverado and GMC Sierra 2500HD and 3500 trucks built with the LLY in the 2004 and 2005 model years.
The rail comes with a new rail pressure sensor fitted in the middle of the rail. It has four threaded high-pressure ports on the side and a threaded line fitting on the end. Shops replace it when the rail leaks or when the fuel system has been contaminated, so debris does not reach new injectors. The left side rail, which carries the pressure relief valve, is Bosch F00R001505. GM changed to different rails for 2006, so this one does not fit LBZ or LMM engines.
Confirm Fitment Before You Order
This rail is for 2004.5-2005 LLY trucks only. A 2004 truck can be an LB7 (8th VIN digit 1) or an LLY (8th VIN digit 2), and they take different rails. GM lists every 2006 and newer truck and van under the later rails (Bosch F00RL00129 and F00RL00143), even a 2006 with VIN digit 2, so send us the VIN and the number off your old rail before ordering for a 2006. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

The rail pressure sensor is already on the rail, so there is nothing to move over from the old one. Keep every port covered until its line goes on. If the rail is being changed because of contamination, change both rails and deal with the source, or the debris comes back. Use the GM service procedure and torque values for the line nuts.

Frequently Asked Questions
Does Bosch F00R001512 come with the rail pressure sensor?
Yes. A new rail pressure sensor is fitted in the middle of the rail. The pressure relief valve is not on this rail: on the LLY it is on the left side rail, Bosch F00R001505.
Will this rail fit a 2006 or newer Duramax?
No. GM lists this rail (97303658) for the 2004 and 2005 model years only. 2006-2010 trucks use a different pair of rails, Bosch F00RL00129 and F00RL00143.
Which side does it fit, what does it replace, and is it new?
It is the right bank (passenger side) rail and it replaces GM 97303658. It is a new Bosch rail, not remanufactured, so there is no core to send back.
How do I know my 2004 truck is an LLY and not an LB7?
Check the 8th digit of the VIN: 2 is the LLY and 1 is the LB7. The LB7 takes a different rail, Bosch F00R001205. Call 530-668-0818 with the VIN and we will check it for you.
