Product Description
FASS INDUIM165G INDUSTRIAL SERIES DIESEL FUEL SYSTEM CLASS 8 SEMI UIM 165GPH
The FASS INDUIM165G Industrial Series provides 165 GPH at ~16–18 PSI for Class 8 / heavy-duty applications using Mechanical Unit Injection (UIM). It combines air/vapor separation with a 2-micron filtration strategy, built-in water separation, and Continuous Fuel Polishing (CFP) for cleaner diesel and longer injector life—backed by a 1,000,000-mile / 5-year warranty.
Fitment & System Notes
- Applications: Class 8, Agricultural, Industrial, Recreational, Highway and Off-road platforms requiring ~16–18 PSI supply pressure.
- Engine type: UIM (Mechanical Unit Injection). Includes oil-pressure safety switch so the pump only runs when the engine is cranking/running.
- Ports: 1/2" fuel ports with gauge and electric heater ports on the base.
- Return: Low-volume return; ties into OEM engine return per the Industrial Series install manual.
