As for the filter light, there is a sending unit beside the schrader valve (third picture, which is typically used for bleeding air, and for test purposes) that is what activates the light. It will be on until the engine starts. I usually pull that sending unit, and use a mighty vac to prime the fuel system from that point. Saves wear and tear on the starter. Makes a troublesome truck start easier when the weather is in the teens.
