FASS Diesel Fuel Systems

What FASS Diesel Fuel Systems does

FASS Diesel Fuel Systems (legal entity Diesel Performance Products Inc.) is a privately-held US manufacturer of aftermarket diesel fuel air separation systems (FASS), filtration products, and related accessories, headquartered in Marthasville, Missouri. The company designs and builds fuel lift pumps and filtration systems that remove air, vapor, and water from diesel fuel while improving fuel flow and pressure to injection systems. It serves diesel-powered light-duty pickup trucks — Ford Powerstroke, GM/Chevrolet Duramax, and Dodge/RAM Cummins — as well as medium/heavy-duty commercial engines from Caterpillar, Cummins, Detroit, John Deere, Mercedes, Paccar, and Volvo. Its product portfolio spans the premium Titanium Signature Series (with Whisper Technology, 2-micron absolute filtration, and patented Performance Radius Cuts and Mass Flow Return), the Drop-In Series (direct factory-filter replacements), the No-Drop Series (bundled with a fuel sump kit), Competition and Industrial Series, plus supporting lines including the FASS Connect wireless digital monitoring system, electric fuel heater kits, an EGR Filter System for Duramax engines, and recurring replacement filter packs. Two wholly-owned subsidiaries — FASS Motorsports (motorsports sponsorship and racing products) and FASS Solutions (technical support) — extend the brand into adjacent operating areas.

The company's underlying technology stack centers on proprietary fuel-air separation and continuous fuel polishing: patented Performance Radius Cuts create smooth-flowing internal passages to prevent eddy currents; Mass Flow Return keeps positive pressure on engine-fed fuel and continuously returns polished fuel to the tank; Whisper Technology reduces system noise while increasing flow; and 2-micron absolute Microglass filtration captures debris below OEM filter capability. Supporting innovations include bolt-on bracket mounting systems that eliminate drilling or welding, ORB black-anodized fittings on Signature Series PLUS systems, and FASS Connect wireless telemetry with five sensor inputs for filter life, fuel pressure, and exhaust gas temperature monitoring.

FASS generates revenue through one-time hardware sales at USD 369–1,199+ per system (varying by series, horsepower rating, and configuration) plus recurring consumable revenue from replacement filter packs at USD 20–151 every ~30,000 miles. Distribution runs through a US-wide authorized dealer network accessed via a 'Become a Dealer' program and dealer-locator tool, alongside direct-to-consumer e-commerce on fassride.com. Customer segments are horizontal: individual diesel truck owners, commercial fleet operators, and diesel performance enthusiasts building engines from stock up to 1500+ HP. Geographic footprint is North America (United States only) with no disclosed international expansion, and the company carries a limited lifetime warranty on its systems while manufacturing domestically in Missouri.
