The Faria Beede combination gauge offers 4 functions: Fuel level (empty - full), Oil pressure (0 - 80psi), Water temperature (100°F - 250°F) and Voltage (10V - 18V). All of these must be measured using US resistance senders which are not included. The Faria Beede multifunction gauge is ideal for space saving on the dashboard, leaving you room to put all your other Faria Beede gauges! This section also contains 5 in 1 gauges, which include an LCD hourmeter.
