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

Revainrating 5 out of 5

Excellent safety measure

For screwing into the oil level outlet. I used a brass nipple and tee to house this switch and oil pressure gauge. If the engine is hooked up properly and the engine stalls, the loss of oil pressure will deactivate the electric fuel pump relay. Good insurance against fuel leaks in your boat or vehicle.

Pros
  • Good value for money
Cons
  • Compatibility
