Fleece Regulated Return Fuel Distribution Block for 2007.5-2018 Ram 6.7L Cummins

Building a twin CP3 6.7L Cummins? You need consistent pressure at the pumps, and this block gives it to you.

The Fleece Cummins Regulated Return Fuel Distribution Block takes Fleece's standard distribution block further by fully integrating a high flow pressure regulator. Paired with high flow aftermarket electric pumps that don't have built in regulation, it provides more consistent fuel pressure at the CP3.

It also adds one extra return port and one extra feed port. The extra return lets you remove the factory fuel pressure relief valve hard line and injector return galley hard line, clearing room for the high flow side draft intakes common on competition engines. The two feed ports let you run two lift pumps so you always have enough fuel volume.

What you get

• Integrated high flow pressure regulator
• Metric straight thread to AN fittings and hose to replace the factory hard lines
• 0-60 psi pressure gauge for quick visual checks of the set-point
• Regulation pressure preset at 20 psi, which Fleece calls optimal for high RPM CP3 operation
• Other pressures available by swapping the internal regulator spring

Tuning with PPEI

PPEI recommends Fleece fuel system parts, and we run them on our own trucks. On a dual CP3 6.7L with PPEI 6.7L Cummins engine tuning, steady supply pressure is what lets the tune pull hard at high RPM. You keep the full power and throttle response the build is made for, and it runs efficiently doing it.
