Engineered specifically for 3rd and 4th Generation Dodge Ram 2500/3500 trucks (2005–2018 5.9L/6.7L Cummins and 2021–2024 6.7L Cummins), the FASS No-Drop Series Fuel Air Separation System (NDTSD07100G) bundles the Titanium Signature Series 100 GPH lift pump with FASS’s single-bolt fuel tank sump kit (SK5501). By packaging these components into a single all-in-one system, this kit completely eliminates the need to drop the factory diesel tank or pull the truck bed to install internal bulkhead tubes or suction straw modifications.

The integrated fuel sump mounts to the base of the fuel tank through a single hole, creating an oversized reservoir bowl with dedicated 1/2-inch NPT suction and return ports. Sucking fuel from the lowest physical point of the tank eliminates 1/4-tank slosh starvation issues commonly encountered under hard acceleration or steep inclines. Fuel is continuously circulated through FASS Whisper Technology and Mass Flow Return (MFR) systems, scrubbing entrained air, vapors, and water while trapping debris down to 2 microns absolute before delivering a steady 16–18 PSI of purified fuel to the CP3 or CP4.2 high-pressure pump.

Key Features & Benefits

• No-Tank-Drop Installation: Combines the Titanium Series lift pump with an external bottom-mount fuel sump, eliminating the labor-intensive need to unbolt the fuel tank or remove the truck bed.
• Eliminates 1/4-Tank Fuel Starvation: Pulls fuel directly from an oversized billet aluminum reservoir bowl at the lowest point of the tank, preventing air-gulping during fuel slosh or low fuel levels.
• 2-Micron Absolute Filtration & Water Removal: Traps fine particulates down to 2 microns absolute and separates over 99% of entrained water, shielding expensive common rail injectors and injection pumps from catastrophic failure.
• Patented Air & Vapor Separation: FASS Mass Flow Return continuously polishes fuel and returns separated air and vapor back to the tank, improving fuel lubricity by at least 10% and smoothing engine idle.
• FASS Whisper Technology (FWT): Advanced internal radius cuts and precision gear machining reduce electric motor decibels without decreasing flow volume.
• Heavy-Duty 1/2" Fuel Lines & Bolt-On Brackets: High-flow 1/2-inch lines minimize fluid friction, mounting directly to factory frame rails with heavy-duty steel bracketry.

Vehicle Fitment & Installation Notes

• 2005–2007 Dodge Ram 2500 / 3500 (3rd Gen) – 5.9L 24V Common Rail Cummins
• 2007.5–2009 Dodge Ram 2500 / 3500 (3rd Gen) – 6.7L 24V Cummins Turbo Diesel
• 2010–2018 Ram 2500 / 3500 (4th Gen) – 6.7L 24V Cummins Turbo Diesel
• 2021–2024 Ram 2500 / 3500 – 6.7L 24V Cummins Turbo Diesel
• 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 configurations may require bracket positioning adjustments.
• Installation Tip: Installing the sump requires cutting a 3-3/4" hole in the flat bottom section of the poly fuel tank; ensure the tank is drained of fuel and all plastic drill shavings are flushed clean before tightening the single-bolt inner clamp ring to 10 ft-lbs.
