So, you need to have really good wiring going back to it. It works from the pulse side of the coil or the tach output on dissy. Can someone help me to understand this? Then you can add safety devices like an oil pressure switch that may not have the current rating to run the pump. This is how the factory switches devices like the fuel pump.
How do you keep an electric fuel pump safe? You do need an oil pressure or inertia switch or both wired into the system to shut the pump off in case of an accident or broken fuel line.
