Engineered for 2005–2018 Dodge Ram 2500 and 3500 diesel trucks powered by the 5.9L Common Rail or 6.7L 24V Cummins engine, the PureFlow AirDog Raptor 4G 150 GPH Fuel Lift Pump (R4SBD053) provides a dedicated high-flow fuel supply for truck owners who retain their factory canister filtration. When Dodge transitioned from engine-mounted pumps to in-tank lift pumps in 2005, reliability improved, but flow output remained insufficient for modified applications. Aftermarket programmers, upgraded injectors, or heavy towing quickly deplete factory line pressure, starving the Bosch CP3 high-pressure injection pump and causing low rail pressure trouble codes (P0087 and P1093).

The Raptor 4G RP-150-4G delivers 150 gallons per hour of continuous fuel flow, easily supporting street, towing, and performance builds from 500 to 800 rear wheel horsepower. Built with an internal diaphragm-style pressure regulator adjustable from 7 to 70 PSI (factory preset to 15–17 PSI), the pump is internally bypassed and requires no dedicated return line back to the fuel tank. The assembly utilizes PureFlow’s quiet 4-bearing motor technology to minimize frame-rail vibration and operational noise. It installs cleanly onto the chassis using a drill-free sandwich plate mounting bracket, pulling fuel through an included Fuel Module Upgrade Kit (1/2" bulkhead fitting) and connecting directly to the engine-mounted factory fuel filter housing.

Key Features & Benefits

• High-Flow 150 GPH Delivery: Outflows factory in-tank pumps to maintain positive inlet pressure under heavy throttle, supporting performance builds from 500 to 800 HP.
• Internally Regulated (No Return Line Needed): Features a built-in adjustable fuel pressure regulator (7–70 PSI, preset to 15–17 PSI) that recirculates fuel internally, eliminating the need to plumb an external return line to the fuel tank.
• Quiet 4-Bearing Motor Technology: 4G intermediate-shaft motor architecture dampens vibration and lowers noise levels to maintain quiet operation inside the cab.
• In-Tank Fuel Module Upgrade Kit: Includes an in-tank suction tube and 1/2-inch bulkhead fitting to bypass the restrictive factory in-tank pump assembly.
• Direct Plumb to Factory Filter Housing: Feeds directly into the engine-mounted factory fuel filter canister, eliminating the purchase and maintenance costs of duplicate spin-on filters.
• Drill-Free Sandwich Plate Frame Mount: Heavy-duty bracketry clamps directly around the factory frame rail using standard hand tools without drilling or welding.
• All-Inclusive Installation Kit: Supplied with a relay control wiring harness, 1/2-inch high-flow fuel lines, quick-connect fittings, and complete mounting hardware.

• Fitment Notice: Engineered for 2005–2018 trucks with the in-tank lift pump configuration. Early 2004 and older 5.9L Cummins trucks equipped with engine-mounted canister lift pumps require part number R4SBD052. Does not fit 2019+ Ram trucks.
• Installation Tip: Install the included Fuel Module Upgrade Kit into the factory fuel tank basket; cut the suction tube at a 45-degree angle approximately 1/4" off the bottom of the basket to prevent low-fuel slosh starvation, and use a fuel pressure gauge to verify line pressure matches your target (typically 15–18 PSI) before road testing.
