Product Description
FASS INDUIM290G INDUSTRIAL SERIES DIESEL FUEL SYSTEM CLASS 8 SEMI UIM 290GPH
The FASS INDUIM290G Industrial Series UIM delivers a massive 290 GPH at ~16–18 PSI with integrated air/vapor and water separation. Engineered for Class 1–8 / Class 8 semi applications that use Mechanical Unit Injection (UIM), it provides 2-micron absolute filtration, whisper-quiet operation, and simplified plumbing via an air-separation return port that ties into the OEM engine return.
Fitment & System Notes
- Application: Class 8 semi / universal industrial use with mechanical unit injection (UIM).
- Examples: Cummins Small/Big Cam I–IV, NTC/STC, L10 platforms (representative UIM engines).
- Fuel pressure: Preset ~16–18 PSI (non-adjustable).
- Filtration: Built-in water separation + 2-micron particulate filtration for injector protection.

FAQ
Is INDUIM290G only for mechanical unit injection engines?Yes. UIM kits are engineered specifically for mechanical unit injection platforms on industrial/Class 8 applications.
What fuel pressure does this system provide?
It is preset to approximately 16–18 PSI and designed to maintain stable supply to UIM systems.
Do I need to add a separate fuel return line?
No. The system includes a dedicated air-separation return port that ties into the OEM engine return, streamlining installation.
What maintenance interval should I expect?
Typical filter service is around 30,000 miles (duty-cycle and fuel quality dependent). Inspect sooner in severe service.
