Engineered specifically for 2003 through 2018 Dodge Ram 2500, 3500, 4500, and 5500 trucks powered by 5.9L and 6.7L Cummins 24-valve common-rail turbo diesel engines, the Industrial Injection Billet CP3 Fuel Pump Access Cover (Part # 24FC04) cures one of the most frustrating common leak points on the Cummins engine platform. The factory front timing gear case uses a threaded plug made of brittle, soft plastic to cover the CP3 drive gear retaining nut. Over repeated heat cycles and routine maintenance servicing, the OEM plastic plug rounds off, cross-threads, or cracks, causing constant oil weeping down the front of the timing case and onto the accessory drive belt.

Machined from high-strength billet 6061-T6 aircraft-grade aluminum, the Industrial Injection 24FC04 cover provides a rigid, permanent solution. It incorporates an integrated, heavy-duty drive hex head that accepts standard shop sockets, preventing the rounded corners and stripped threads common to the factory plastic cap. In addition to delivering a leak-free seal against the timing case, the precision-milled aluminum cap adds a clean billet accent to the front of the Cummins engine bay.

Key Features & Benefits

• Eliminates Front Timing Case Oil Leaks: Replaces the failure-prone factory plastic plug that cracks, warps, and seeps engine oil down the front cover.
• Stripped-Thread Prevention: Features a sturdy CNC-machined hex head that easily accepts standard sockets without rounding off or stripping out during removal.
• Precision CNC Billet Aluminum: Machined from solid 6061-T6 aluminum stock for structural integrity, precise thread pitch, and reliable seal compression.
• Reuses Factory O-Ring or Seals: Designed to match OEM timing cover boss dimensions for a clean, direct thread-in replacement.
• Dresses Up the Engine Bay: Adds an attractive machined billet aluminum highlight to the front gear housing.

• Installation Tip: Clean the internal threads of the front timing case access port thoroughly with a lint-free shop towel before installation to remove grit. Transfer or install a fresh nitrile/Viton sealing O-ring onto the billet plug groove, lightly lubricating it with clean engine oil. Thread in hand-tight first to confirm alignment, then torque gently until the O-ring compresses flush against the housing face (do not over-torque into aluminum case threads).
