The two fuel filter inlets come from the two fuel tanks. Each tank has a fuel pump. Each fuel pump has a check valve that prevents the fuel from back-flowing when the pump is turned off. So fuel flow from a tank is selected by powering up the fuel pump in that tank. One of the two fuel filter outlets is connected to a Westach 387-30V2-C fuel pressure sensor. The fuel pressure sensor comes with the Westach D1642C8-37 30psi fuel pressure 2" gage kit. I know the Westach gages are pricey but they are the best quality automotive gages I have seen. Well worth the price.
