Review on πŸ”’ Holley 12-810 Fuel Pump Safety Pressure Switch: Ensuring Optimal Fuel System Protection by Daniel Truett

Revainrating 5 out of 5

Used to convert mechanical fuel pump to electric

Converted to E-Fuel on my 7.3 Powerstroke and used it to cycle the pump on and off (via relays of course) and worked great for 6 years. months so far. It is a direct replacement for the plug on the oil cooler on this engine. Just screw it in and as soon as you start it it will feel the oil pressure, turn the pump on and turn it off once the engine is off. I have a manual toggle switch wired to the relay and also to the priming, but it's not needed unless I'm working on the fuel lines or draining the tank.

Pros
  • Weight
Cons
  • Some little things
