Product Description
The CUMMINS 3928898 OEM P7100 INJECTION PUMP SUPPORT BRACKET is the genuine factory support brace designed for 1994-1998 Dodge Ram 5.9L 12-valve Cummins engines equipped with the Bosch P7100 injection pump. This critical support bracket stabilizes the P-pump assembly by bracing it to the engine block, helping reduce vibration, prevent mounting ear fatigue, and maintain proper pump alignment.
Over time, missing or damaged support brackets can allow excessive movement of the heavy P7100 injection pump, potentially contributing to mounting stress, gear alignment issues, and premature wear. Installing the genuine Cummins 3928898 bracket restores factory support and helps improve long-term fuel system durability under towing, daily driving, and performance applications.
Manufactured to OEM Cummins specifications, this support bracket provides precise fitment and OE-grade durability for reliable installation on all 1994-1998 12-valve Cummins applications using the mechanical Bosch P7100 injection pump.

WHY IS THE P7100 SUPPORT BRACKET IMPORTANT?
The Bosch P7100 injection pump is a heavy mechanical fuel pump that experiences vibration and stress during engine operation. Without proper support, the pump housing and mounting ears can experience excessive load, potentially causing fatigue, alignment problems, or premature wear. The OEM support bracket helps stabilize the pump assembly and improve long-term reliability.
