Holley Safety Fuel Pressure Switches
It's always a good idea to place a safety switch in the circuit when installing an electric fuel pump. Holley safety fuel pressure switches will ensure the electric pump will not work unless the engine has oil pressure. It will prevent the pump from running in a situation where the motor may stall with the ignition on. Wiring the switch through the starter solenoid circuit energizes the pump on engine start-up. After the engine is running, the switch continues to provide power to the pump as long as there is oil pressure to keep the switch turned on.

DeatschWerks Hobbs Switches
DeatschWerks Hobbs switches are adjustable, pressure-activated electrical switches designed to trigger secondary systems—such as fuel pumps, nitrous systems, or warning lights—based on intake manifold boost pressure. They're crucial for high performance, forced-induction vehicles to ensure adequate fuel delivery, preventing engine lean-out by activating additional pumps only under boost. The switches are available in a variety of pressure ranges. Additional details: * Functionality: Normally open (or closed) switches that activate at a specific, adjustable pressure threshold * Components: Feature a durable, corrosion-resistant metal body with a standard 1/8 in. NPT threaded connection for mounting * Installation: Included pigtail wiring harness simplifies integration into vehicle electrical systems * Versatility: Suitable for various automotive applications, Hobbs switches help manage electrical load by keeping secondary systems off during low-demand, vacuum-driven driving
