Product Description
The CUMMINS 3946440 OEM FUEL LINE BRACKET / TUBE BRACE is the original equipment-manufacturer (OEM) bracket designed to secure the injection pump fuel lines on 5.9 L ISB (VP44) engines used in 1998.5–2002 Dodge Ram 2500/3500 trucks. This tube brace mounts on the top of the intake plenum and holds the high-pressure fuel lines in their factory configuration — preventing vibration, chafe, and mis-routing that can compromise fuel delivery or lead to premature wear. Built with durable steel to withstand engine heat and vibration, this bracket restores the factory routing and supports proper line alignment. Ideal for anyone rebuilding or repairing a 5.9L VP44 fuel system and wanting true OEM fit and function, not a generic aftermarket replacement.
