FASS Connect Digital Monitoring System - PRE-ORDER - FC2001K

Part # FC2001K

The FASS Connect and related accessories will be available for pre-order and are expected to ship by January 31, 2026.

The FASS Connect Digital Monitoring System was designed for a simple, clean installation and gives the ability to monitor your FASS Fuel System’s filter life, fuel pressure, and other drivetrain parameters using a powerful wireless technology.

The FASS Connect has 5 sensor inputs that allow you to utilize a 0 to 100 PSI pressure, -40° to 260° temperature, and a 2,000° exhaust gas temperature sensor. Not only is the FASS Connect a monitoring system, it also has 2x relay trigger outputs that allow you to power-on your FASS Fuel Heaters or other accessories like auxiliary lights right from the FASS Connect APP!

The FASS Connect ECU communicates wirelessly to the FASS Connect Gauge and FASS Connect APP giving you an ultra-clean installation and flexibility on applications where the Gauge must be mounted further from the ECU than on a normal pickup truck.

This kit includes the FASS Connect ECU, the FASS Connect Gauge, and a 0-100 PSI fuel pressure sensor (additional sensors available for purchase as accessories).

Adding a second fuel pressure sensor to your FASS System allows you to monitor the filter life of your Extreme Water Separator in real-time, letting you know when it’s time to change your filters. Sensors can be mixed and matched to run any combination of the available accessory sensors that you need to best suit your application.
