The OP needs to take a step back and diagnose a bit more methodically. He supposedly has no power to the fuel pump, the fuel pump is no good, the sending unit doesn't work and the syphon jet doesn't work (or isn't there) and he's wrong on most of those assumptions. The pump won't work if there is no power, the guage won't necessarily respond directly to working the float up and down, there is a small amount of fuel in the fuel pump well which might be normal, etc.
