    MM3 - Fuel Line Pressure?

    Can the MM3 Tuner read fuel line pressure from the pump?

    I am putting on a FASS system and want to know if I have to get an aftermarket gauge or if my MM3 has a spot for that senor to the plugin.

    Thanks.

    To the best of my knowledge, the MM3 does not have the capability of monitoring the lift pump pressure.

    You will need to install a separate gauge and tap inline or install a Big Line Kit.
