Another no fuel mystery

Gas will not run into the filter when you press the pedal, unless you are cranking or have the key on. If you have a mechanical pump it should flow during cranking. If it is electric it should flow on key on. It could be a diaphragm in the fuel pump, clogged filter, old gas, etc... pull off the fuel line, put it in a jar and crank it a few time to see if there is flow. If not, start back tracking to see if there is a plugged line or filter. If not you need a pump. It may not even be a fuel problem, but going with your guess I would check these things first.
