Read and follow all installation instructions
FuelCAN is a compact interface for translating an analogue
fuel level sender signal into digital SAE J1939 CANbus data.
The device allows integration of standard fuel level senders
into modern ECU-based engine instrument and control
systems.
FuelCAN modules have three inputs (only one of which is
connected at any one time): input 1 is configured for use with
Murphy ES series resistive fuel level senders; inputs 2 and 3
can be used with fuel level senders having compatible
resistance ranges.

Input 1 (Murphy) 240
Input 2 240
Input 3 10
FuelCAN inputs can also be factory-configured for use with
non-standard fuel level or resistive senders. Please note
that minimum order quantities apply for custom solutions.
A rear facing LED indicates input and CANbus status.
FuelCAN is compact and light enough to be incorporated
into wiring harnesses, but can also be surface mounted via
four case holes. The polycarbonate case is fully sealed in
epoxy resin for high impact and environmental resistance.
These instructions relate to Murphy part number 79.70.0006.
FuelCAN modules with other stock codes may include
modified input scaling or CANbus/J1939 data parameters.
