Fass Connect Universal Digital Monitoring System
Fits: Universal
The FASS Connect Lite Digital Monitoring System is designed for a simple, clean installation and lets you monitor your FASS Fuel System’s filter life, fuel pressure, and other drivetrain parameters using powerful wireless technology.
The FASS Connect Lite has 5 sensor inputs that support a 0–100 PSI pressure sensor, a –40° to 260° temperature sensor, and a 2,000° exhaust gas temperature sensor. In addition to monitoring, it includes 2 relay trigger outputs to power FASS Fuel Heaters or other accessories, such as auxiliary lights, directly from the FASS Connect App.
The FASS Connect App can monitor up to 8 parameters at a time—5 sensor inputs, filter life, GPS speed, and battery voltage.
The FASS Connect ECU communicates wirelessly with the FASS Connect App, enabling an ultra‑clean installation and greater flexibility.
This kit includes the FASS Connect ECU and a 0–100 PSI fuel pressure sensor (additional accessory sensors available separately).
Adding a second fuel pressure sensor enables real‑time monitoring of the Extreme Water Separator's filter life, letting you know when service is needed. Sensors can be mixed and matched to create any combination you need for your application.
