Engineered specifically for 3rd Generation (2005–2009) Dodge Ram 2500 and 3500 diesel trucks powered by the 5.9L Common Rail or 6.7L 24V Cummins, the FASS Signature Series Adjustable Fuel Lift Pump (FASD07290G) provides competition-grade fuel delivery for dedicated race trucks, heavy sled pullers, and extreme dual-CP3 setups. In extreme-horsepower applications, factory fuel lines and in-tank transfer pumps experience massive vacuum drops that introduce severe cavitation, starving expensive high-pressure injection pumps. The FASD07290G satisfies heavy fuel demands by delivering an uninterrupted 290 gallons per hour of low-pressure diesel fuel.

Designed for setups that utilize the factory fuel filter housing or dedicated external secondary filtration, this pump-only assembly offers mechanical fuel pressure adjustability from 1 to 75 PSI, allowing builders to dial in exact target pressures for specialized racing setups. A built-in boost compensation port connects directly to the intake manifold, referencing boost pressure to dynamically increase fuel delivery under wide-open throttle to eliminate fuel pressure drop during high boost. Equipped with FASS Whisper Technology (FWT) to lower operating noise, the unit includes an integrated 1/8" NPT fuel pressure gauge port and an unrestricted BHF-1005 billet bulkhead and 5/8" PTFE suction tube kit that installs directly into the OEM tank module.

Key Features & Benefits

• Massive 290 GPH Flow Delivery: Supplies 290 gallons per hour of continuous diesel fuel flow to support competition and race engines producing 1,200 to 1,500+ horsepower.
• Wide-Range Pressure Adjustability (1–75 PSI): Mechanically adjustable pressure regulator allows custom pressure tuning to match specialized competition injection pumps and dual-CP3 kits.
• Manifold Boost Compensation Port: Uses manifold boost pressure to mechanically increase pump delivery under full throttle, holding rock-steady rail supply under high engine load.
• Integrated Diagnostic Pressure Port: Built-in 1/8" NPT port facilitates direct plumbing of mechanical or digital fuel pressure sensors for real-time monitoring.
• FASS Whisper Technology (FWT): Precision-engineered internal radius cuts and tighter gear clearances significantly reduce motor operational noise without restricting volume.
• High-Flow 5/8" Bulkhead & Suction Tube Kit: Includes 6061-T6 billet aluminum bulkhead fittings and an oversized 5/8" PTFE suction tube to draw maximum fuel volume directly from the tank module without cutting the filler neck.
• Dedicated Pump-Only Design: Engineered specifically for trucks running external filter heads or factory filter canisters, avoiding the cost of redundant spin-on filter bases.

Vehicle Fitment & Installation Notes

• 2005–2007 Dodge Ram 2500 (3rd Gen) – 5.9L 24V Common Rail Cummins
• 2005–2007 Dodge Ram 3500 (3rd Gen) – 5.9L 24V Common Rail Cummins
• 2007.5–2009 Dodge Ram 2500 (3rd Gen) – 6.7L 24V Cummins Turbo Diesel
• 2007.5–2009 Dodge Ram 3500 (3rd Gen) – 6.7L 24V Cummins Turbo Diesel
• Fits Model Years: 2005, 2006, 2007, 2007.5, 2008, 2009
• Fitment Notice: Compatible with 3rd Gen trucks equipped with the factory in-tank fuel pump. This is a standalone lift pump and must be routed through the OEM filter housing or an aftermarket fuel filtration head (such as the S&S Diesel regulated filter head). 2010–2014 4th Gen trucks require part number FASD05290G.
• Installation Tip: A fuel pressure gauge must be plumbed into the 1/8" NPT port prior to adjusting line pressure; adjust the pressure set screw with the engine idling until target positive pressure is achieved, then tighten the locknut securely before connecting the boost compensation line to the intake manifold.
