Safety-cut-out relay for electric fuel pump
€69.00*
For safety reasons, the fuel pump must not pump when the engine is at a standstill.
What is no issue with a mechanical fuel pump becomes interesting when retrofitting to an electric fuel pump.
Here, a shutdown relay must ensure that the pump does not run when the engine is stationary. Legislation made this mandatory for good reasons.
In the event of an accident, no one wants fuel to be pumped out of the tank to act as a fire accelerant.
When the ignition is switched on, the relay switches the fuel pump on for about 2 seconds and then shuts it down again.
This avoids a risk of overheating of the pump. The relay then switches on only when a running motor is detected via the connection to the ignition coil. If the engine stops, the relay disconnects the power supply of the fuel pump.
Can be used with conventional ignition systems. The resistance of the ignition coil must not be less than 2 ohms at the primary winding.
Compatible with 123 Ignition, Bosch 009, contactless ignition Ignitor, interrupter contact etc.
