Cummins Fuel Pump Block Plate

Simplify and clean up your Cummins engine bay with the G&R Diesel Billet Aluminum Block Plate. This precision-machined component provides an elegant, reliable solution for blocking the factory engine block port originally used for the mechanical fuel supply pump on 12-valve engines or as a CCV drain on later models.

Premium Construction & Materials

CNC-machined from high-quality billet aluminum, this block plate is available in a clean raw aluminum finish or a sleek anodized black option to match your build’s aesthetic. It features a robust, one-piece design engineered for a perfect seal and long-term durability in the demanding diesel environment. The plate includes a high-quality O-ring seal (superior to the factory paper gasket) and zinc-plated flange head bolts for secure, corrosion-resistant installation.

Key Features & Benefits

• Fuel Pump Delete: Ideal for 12-valve Cummins engines when converting to an electric lift pump. Allows complete removal of the block-mounted mechanical fuel pump, freeing up space and eliminating a potential leak point.
• CCV System Simplification: On 2006+ 5.9L and 6.7L Cummins engines, this plate enables the elimination of restrictive factory plastic CCV drain lines (stock Y tube) when paired with a G&R Diesel billet aluminum valve cover. This results in a cleaner engine bay and a more reliable crankcase ventilation setup.
• Superior Sealing: Utilizes a premium O-ring for a positive, leak-free seal far more dependable than traditional paper gaskets.
• Complete Hardware Kit: Includes all necessary zinc-plated flange head bolts for straightforward installation.
• Finish Options: Available in raw machined aluminum or anodized black for a custom look.
