We recently released the new
Universal Drop-In Series Fuel System for commercial diesel trucks, and to help customers better understand the system and installation process, we’ve put together a detailed installation overview video—embedded right here in this article.
Designed specifically for commercial applications, the Universal Drop-In Series brings proven FASS air and vapor separation technology to a wide range of diesel trucks and equipment without requiring a complete custom fuel system redesign
Why the Universal Drop-In Series Matters
Modern commercial diesel engines rely heavily on clean, properly conditioned fuel.
Unfortunately, factory fuel systems often allow entrained air and vapor to remain in the fuel supply, which can contribute to:
- Reduced fuel lubricity
- Inconsistent fuel pressure
- Hard starts and rough operation
- Premature injector and fuel system wear
The
FASS Universal Drop-In Series Fuel System is engineered to remove air and vapor before fuel reaches the injection system, improving fuel lubricity at LEAST 10%, and ultimately tripling the life of injection components.
About the Installation Overview Video
Because this is a universal commercial truck product, installation procedures can vary depending on:
- Truck make/model
- Tank configuration
- Engine
- Fuel system layout
For that reason, this video is designed as an
installation overview, not a strict step-by-step guide.
In the video, we walk through:
- Core system components
- Mounting concepts and layout considerations
- Fuel line routing
- Wiring basics
- General installation best practices
The goal is to help installers and fleet operators better understand how the system integrates into a wide range of commercial diesel applications.
Built for Commercial Diesel Applications
The Universal Drop-In Series was developed for:
- Semi trucks
- Medium-duty commercial trucks
- Fleet vehicles
- Industrial diesel applications
By improving fuel quality and reducing aeration, the system maximizes MPG, power, throttle response, and reliability—while reducing soot outpot/regens (if DPF equipped).
