This simple to install Hobbs switch can be used to run a secondary fuel pump or provide an additional level of WMI protection. Available in both 1/8" NPT and vacuum nipple, it's normally closed and will open at the preset 5psi. The switch is rated for up to 6amps. If used as a WMI flood safety we suggest running the solenoid ground through it so the solenoid can only open if the WMI system requests flow AND you're making at least 5psi. For those using it to trigger a secondary fuel pump, we suggest using it to trigger a 30amp automotive relay.
