FASS CFDB1001K CUMMINS FUEL DISTRIBUTION BLOCK

Product Description

FASS CFDB1001K Cummins Fuel Distribution Block is engineered for high-performance common-rail Cummins builds running single, dual, or up to three CP3 pumps. Its internal flow paths are shaped to deliver smooth, equal fuel flow and pressure to each CP3, helping stabilize rail pressure under load. The block mounts directly to the engine block on 5.9L and 6.7L Cummins common-rail applications and is a clean way to plumb multi-pump setups.

• Supports single, dual, or triple CP3 configurations
• Equalized distribution to each CP3 for consistent rail pressure
• Direct-mount solution for a tidy, leak-resistant layout
• Ideal companion to FASS Titanium / No-Drop fuel systems

Fitment

• 2003–2007 Dodge Ram 5.9L Cummins (Common Rail)
• 2007.5–2022+ Ram 6.7L Cummins (Common Rail)

Note: This block cannot be used with the factory metal fuel rail return line or cylinder head return line. Re-plumb returns using braided hose or FASS Push-Lok-style line for proper clearance and flow.

FAQ

Will this work with a single CP3, or is it only for dual/triple setups?

It’s designed for high-flow multi-pump builds but can also be used on single or dual CP3 configurations.

Do I keep the factory metal return lines?

No. The factory metal fuel rail and cylinder head return lines are not compatible. Re-route returns using braided or Push-Lok-style hose for proper fitment.

Does the block include fittings and hardware?

Core hardware is included by the manufacturer for engine-block mounting. Line/fitting choices vary by build—pair with the FASS regulators and suction tube kits linked above for a complete system.

What fuel systems pair best with this distribution block?

FASS Titanium Signature Series / No-Drop Series systems are popular choices to maintain steady supply to single, dual, or triple CP3 configurations.

Is any tuning required after install?

The block itself doesn’t require tuning, but multi-pump setups and rail pressure targets should be validated in your calibration.
