Engineered for 2005–2018 and 2021–2024 Dodge Ram 2500 and 3500 diesel trucks powered by the 5.9L Common Rail or 6.7L Cummins engine, the FASS No-Drop Series Fuel Air Separation System (NDTSD07165G) pairs the Titanium Signature Series 165 GPH high-flow lift pump with FASS’s single-bolt fuel tank sump kit. By bundling the sump directly into the package, this complete kit eliminates the difficult labor of dropping the factory fuel tank or unbolting the truck bed to access the factory sending unit.

Designed to fuel modified street, heavy towing, and competition applications producing between 600 and 900 horsepower, the 165 GPH flow rating ensures continuous positive feed pressure to CP3 or modified high-pressure injection pumps under maximum engine demand. The bottom-mounted billet sump pulls fuel from the lowest point in the tank to eliminate 1/4-tank fuel starvation and slosh issues. Simultaneously, FASS Whisper Technology and Mass Flow Return (MFR) systems continuously scrub the diesel charge, purging air, vapor, and over 99% of entrained water while filtering debris down to 2 microns absolute.

Key Features & Benefits

• No-Tank-Drop Installation: Bundles the Titanium Series 165 GPH pump with an external bottom-mount sump kit, eliminating the need to lower the tank or pull the bed.
• Supports 600–900 Horsepower: Delivers 165 gallons per hour at a steady 16–18 PSI, supplying high-volume fuel delivery for larger injectors, upgraded turbos, and dual-CP3 setups.
• Eliminates 1/4-Tank Starvation: Billet aluminum sump draws fuel from the very bottom of the tank, preventing cavitation and low-fuel slosh aeration.
• 2-Micron Absolute Particulate Filtration: Traps microscopic soot and debris down to 2 microns absolute, significantly extending the life of expensive common rail injectors.
• Over 99% Water Separation: High-efficiency water separator blocks free and emulsified water from entering the high-pressure fuel rail.
• Patented Air & Vapor Removal: Mass Flow Return continuously polishes fuel and returns entrained air to the tank, increasing fuel lubricity by at least 10% and smoothing idle.
• FASS Whisper Technology (FWT): Precision-engineered radius cuts and acoustic baffling drastically reduce operating motor noise without restricting high flow rates.

• Fitment Notice: Does not fit 2019–2020 Ram trucks without custom fuel line plumbing adaptations due to factory low-pressure line variations (use FASS part series D12 for 19–20). Cab & Chassis trucks may require bracket modifications.
• Installation Tip: When cutting the 3-3/4" hole in the base of the tank for the sump assembly, ensure the tank is drained and deburred thoroughly, and torque the inner single-bolt clamp ring evenly to 10 ft-lbs to ensure an airtight gasket seal.
