2007.5-2018 Ram 6.7L Cummins Injector Connector Tube | Genuine Bosch F00RC00647

Genuine Bosch high-pressure connector tube for the 6.7L Cummins. This is the steel tube that carries fuel from the rail, through the cylinder head, into the injector, sealing metal-to-metal at both ends. Six are required per engine, one per cylinder.

Fitment

Bosch lists this one connector across the entire 6.7L Ram range, pickup and cab & chassis:

• Ram 2500 & 3500 pickup, 2007.5–2018 (injectors 0986435518 and 0986435621)
• Ram cab & chassis 3500/4500/5500, 2007–2018 (injectors 0986435519, 0986435574, 0986435573)

Cab & chassis does not take a different tube from the pickup. This is a common misconception.

This tube does not fit the 5.9L. For 2003–2007 5.9L Cummins you need Bosch F00RJ01572.

Why a new tube goes in with a new injector

The connector tube sits in the cylinder head and seats in the injector’s inlet port. Install instructions for the 5.9L and 6.7L Cummins say that when a new injector goes in, a new connector tube must be used with it.

A tube can look perfect and still be finished. What is worn out is a shape you cannot see.

Symptoms of a failed connector tube

• Hard starting, particularly when hot
• A miss on one cylinder that follows the tube rather than the injector
• Raw diesel smell after a hard pull with no visible external leak
