The Faria Beede oil pressure gauge measures from 0 to 80 PSI and monitors engine or transmission oil pressure. The dual scale dial displays PSI as a primary and secondary bar. The oil pressure gauge displays the pressure at which oil enters the engine from the pump. This gauge warns of probable engine failure caused by a depleted oil supply, failure of the oil pump, burned-out bearings, burst oil lines, or other factors that may be indicated by a decrease in oil pressure.
