    remove the fuel filter and place a pressure gauge on the pump line side should be 60 psi [or more] with the pump run of 2 sec.also should hold pressure.

    you don't need a diagram because the lines are of a different size.vapor the largest/ return the smallest.

    The flex lines that run up the back of the engine can rust inside or catch crap and plug up. Take off all the lines you can and back blow with air. Do not let it blow back into the filter or pump though.
