Product Description

The FASS FC2001K Connect Digital Monitoring System is an advanced wireless monitoring solution designed for use with FASS fuel systems on diesel-powered vehicles. It provides real-time visibility into key performance data such as fuel pressure, filter life, and additional engine parameters through a dedicated in-cab gauge or smartphone application.

This system uses a wireless ECU to transmit data from multiple sensors to the display, eliminating the need for complex wiring through the vehicle cabin. It supports up to five sensor inputs, allowing users to expand monitoring capabilities with optional EGT, temperature, and additional pressure sensors. Dual relay outputs also allow control of accessories such as fuel heaters or auxiliary devices directly through the system.

Designed as a universal upgrade for vehicles already equipped with FASS fuel systems, the FC2001K enhances diagnostic capability and system awareness without modifying the fuel delivery hardware itself. It is ideal for diesel truck owners who want detailed insight into fuel system health and performance under towing, hauling, or high-performance driving conditions.
