Why convert your LML's fuel system from a CP4 to a CP3? Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms—resulting in costly repairs for owners when a CP4 fails. You can improve your LML Duramax's reliability and fueling capability, as well as avoid costly failure with Fleece Performance LML CP3 conversion kits. They provide OEM fit-and-finish features, like Fleece's exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and their valley feed line to support aftermarket lift pump applications. Fleece Performance LML CP3 conversion kits are offered with or without pump and the pump kits come in two different style pumps—a Bosch CP3 injection pump or Bosch CP3 pump with heavy-duty 10mm cam. Choose the kit that is right for you. All kits include: * CP3 to rail high pressure fuel line * High-flow CP3 feed and return fuel fittings * Preformed fuel feed and return fuel hoses * CP3 mounting adapter * Dosing injector distribution block, feed and return lines * FCA extension harness * Low pressure fuel feed line * Hardware kit

The opening and closing of fuel injectors create pressure pulses in the fuel rail which can lead to unstable fuel pressure. To achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. Radium Engineering fuel system pulsation dampers feature an internal diaphragm that will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the rpm range and can often help idle surge, especially with high-flow injectors. They also help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out. Kits come with different male adapter fittings. Choose the proper one for your fuel feed hose. Features: * Anodized aluminum housing with a large 0.69 in. center bore * Two in-line inlet/outlet ports machined with 3/4 in.-16 UNF threads for 8 AN ORB fittings * At 1.98 in. tall, the FPD-R can be used in space-constrained applications * FPD-R base pressure requirement equals 40 to 70 psi (static) * Includes adapter fittings which seal to the billet housing using Viton® O-rings * An 1/8 in. NPT female port is threaded into the center of the fuel pulse damper * Safe for use with all fuel types, including alcohol blends such as E85 * Vacuum/boost reference port allows for proper performance even at elevated fuel pressures

The Radium Engineering Direct Mount Regulator (DMR) is a compact high performance adjustable EFI fuel pressure regulator designed with a unique highly versatile mounting system. It can be mounted directly to a compatible fuel rail port using the included 360 degree swiveling adapter, or mounted remotely away from the fuel rail. The compact size fits in areas with limited space without sacrificing performance. This regulator is safe to use with all gasoline and ethanol blends of fuel. The main inlet port on the regulator is female threaded for 6 AN ORB. A swiveling double-ended adapter is included with the kit that allows the regulator to be used in any compatible 8 AN ORB fuel rail port, such as those found on Radium Engineering fuel rails. The return port on the bottom is threaded for 6 AN ORB. The provided 90-degree 6 AN male fuel return fitting can swivel 360 degrees, permitting a multitude of mounting configurations. Other adapter fittings can be installed in the return port if needed (sold separately). Unlike the previous generation, this DMR has two 1/8 in. NPT side port locations that can be used with a pressure gauge, transducer, temperature probe, etc. Two 1/8 in. NPT plugs are provided. Fuel pressure is dialed in using the preloaded set screw on top of the regulator. Two interchangeable orifices are included with calculated flow diameters to match the fuel pump flow to the regulator. This permits the DMR to be used with practically any horsepower engine. This added precision will resist diaphragm flutter and optimize pressure stability. This design has been tested to regulate over 1,200 liters per hour. What's included: * Fuel Pressure Regulator (black or green anodized top) * Swiveling inlet adapter fitting (for 8 AN ORB fuel rail) * PTFE impregnated 1/8 in. NPT plugs (x2) * 6 AN male swivel (for return line) * Return orifices (silver orifice pre-installed)

The FX-S Series fuel pressure regulators from Go Fast Bits join their existing line of successful fuel delivery products—built with the same precision, machining quality, and reliability that is the foundation of GFB's reputation. Go Fast Bits FX-S fuel pressure regulators are available in different model configurations to meet the needs of your specific setup. The 8050 models have multiple inlet/gauge ports that allow for a wide range of fuel system setups beyond the usual inlet/outlet, including parallel fuel rail or returnless "deadhead" systems. The two gauge ports allow you to run a mechanical fuel pressure gauge and an ECU fuel pressure sensor if you want. GFB also offers the 8051 model—a direct drop-in Bosch replacement for common Bosch regulators that clip into the fuel rail, rather than replacing the entire fuel rail or using an adaptor with a separate fuel pressure regulator. By simply clipping in the FX-S 8051 fuel pressure regulator will allow you to run a much larger pump setup even with the factory rail. Whether you run pump petrol/gasoline, Ethanol, Methanol or Diesel—Go Fast Bits has you covered—no matter what your fuel pressure regulatory requirements are! Features of FX-S Series fuel pressure regulators: * Billet aluminum construction with black anodized finish * Features double-layer diaphragm that has twice the reinforcing material of the single layer type used in most regulators * Valve seat has a soft, more compliant yet resilient material that positively seals and holds fuel pressure for easier startup vs. conventional aftermarket fuel pressure regulators that utilize metal-to-metal valve and seat * PTFE co-polymer seat with spherical stainless valve retains fuel pressure longer after shutdown * Spring pre-load adjustment screw is O-ring sealed and does not leak vacuum/boost * Completely serviceable
