The FASS Connect Lite Digital Monitoring System was designed for a simple, clean installation and provides the ability to 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 allow the use of 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 for powering 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, providing 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 allows 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.
