The Holley 12-810 is a fuel pump safety pressure switch that protects an engine if it loses oil pressure. Wired into the electric fuel pump circuit alongside the oil pressure switch, it removes power from the pump when oil pressure drops, stalling the engine from fuel starvation rather than letting it run without lubrication. It is a universal switch for all electric fuel pumps with a 2 to 100 PSI working range.
