Description
Overview
The FASS Fuel Systems Cummins Fuel Distribution Block (CFDB1001K) is a precision-engineered billet component built to manage fuel delivery across demanding common rail applications. Designed for high performance builds running up to three CP3 injection pumps, it works equally well on single or dual CP3 setups, giving you a scalable foundation whether you’re upgrading now or planning a bigger fueling package down the road. Machined from 6061 T-6 billet aluminum, this distribution block is engineered to handle the pressure and flow demands of a serious Cummins fuel system.
What sets this block apart is its uniquely shaped internal design. FASS engineered a smooth path of flow to each CP3, ensuring equal distribution of both fuel pressure and fuel flow across every pump. That balanced delivery is critical when you’re feeding multiple CP3s, helping each pump receive a consistent, reliable supply of fuel.
Key Benefits
The CFDB1001K bolts directly to the engine block of 5.9L Common Rail and 6.7L Common Rail Cummins engines, keeping installation clean and integrated with your factory mounting points. It arrives with the mounting hardware needed to secure it in place, and its comprehensive port layout is designed to centralize your main fuel supply, CP3 feeds, and return lines into a single, purpose-built manifold.
- Machined from durable 6061 T-6 billet aluminum
- Supports up to three CP3 pumps, and works on single or dual CP3 applications
- Uniquely shaped for a smooth path of flow to each CP3
- Ensures equal distribution of fuel pressure and fuel flow
- -10 main fuel inlet and three -8 CP3 feed ports
- -8 fuel return outlet with four -6 fuel return inlet ports for CP3 and cylinder head return
- Two 1/8-inch NPT gauge ports for monitoring
- Includes mounting hardware; sold as each
Ports & Plumbing
The distribution block is configured with a -10 main fuel inlet, three -8 CP3 feed ports, and a -8 fuel return outlet. Four -6 fuel return inlet ports handle both CP3 return and cylinder head return, while two 1/8-inch NPT gauge ports let you monitor pressure directly at the block. Please note that this block cannot be used with the factory metal fuel rail return line or the factory cylinder head return line; the system will need to be plumbed with braided fuel line or FASS Push-Lok fuel line to complete the return circuit.
Fitment
The CFDB1001K is built specifically for Cummins Truck/SUV applications, bolting directly to 5.9L and 6.7L Common Rail Cummins engine blocks. It is sold individually (each) and includes the mounting hardware required for installation.
