Fleece Performance Regulated Return Fuel Distribution Block

2007–2018 Dodge Ram 2500/3500 5.9L & 6.7L Diesel

Part #: FPE-CRR-20-0806

Overview

The Fleece Performance Regulated Return Fuel Distribution Block is a precision-engineered upgrade designed specifically for Dodge Ram 2500 and 3500 models equipped with 5.9L and 6.7L Cummins diesel engines from 2007 through 2018. This advanced fuel distribution block integrates a high-flow pressure regulator, elevating the performance of your fuel system by delivering consistent and stable fuel pressure to the CP3 injection pump. Ideal for enthusiasts running high-flow aftermarket electric fuel pumps without built-in pressure regulation, this component ensures optimal fuel delivery for enhanced engine reliability and power output.

By replacing factory hard lines with metric straight thread to AN fittings and hoses, the block simplifies plumbing while improving clearance for high-flow side draft intakes commonly used in competition and high-performance diesel applications. This upgrade is essential for those seeking to maintain precise fuel pressure control and maximize the efficiency of dual lift pump setups.

Key Features

The Fleece Performance Regulated Return Fuel Distribution Block offers a range of features tailored to high-performance diesel fuel systems:

• Integrated high-flow pressure regulator preset at 20 psi for optimal CP3 pump operation at high RPMs
• Additional return line port to eliminate factory fuel pressure relief valve hard line and injector return galley hard line, improving intake clearance
• Two feed line ports to support dual lift pump configurations, ensuring ample fuel volume under demanding conditions
• Includes metric straight thread to AN fittings and hoses for seamless replacement of factory hard lines
• 0-60 psi pressure gauge included for quick and accurate fuel pressure monitoring
• Pressure regulation can be customized by swapping internal regulator springs to suit specific tuning needs
• Designed for use with 6.7L fuel rails and dual 6.7L CP3 pumps for maximum compatibility

Construction & Design

Crafted from durable, high-quality materials, the Fleece Performance fuel distribution block is engineered to withstand the rigors of high-pressure diesel fuel systems. The robust construction ensures long-lasting reliability and resistance to corrosion and wear. Precision machining guarantees a perfect fit and leak-free connections when installed with the included AN fittings and hoses. The design thoughtfully integrates additional ports to accommodate advanced fuel system setups without compromising factory component clearance or vehicle packaging.

Installation & Fitment

Installation of the Fleece Performance Regulated Return Fuel Distribution Block is straightforward for experienced diesel technicians and enthusiasts familiar with fuel system modifications. The kit replaces factory hard lines with supplied metric to AN fittings and hoses, requiring removal of the factory fuel pressure relief valve hard line and injector return galley hard line. This modification provides necessary clearance for high-flow side draft intakes and facilitates dual lift pump setups. Note that the kit does not include 1/2" (-8AN) or 3/8" (-6AN) fuel lines needed to feed the distribution block or return fuel to the tank, which must be sourced separately.
