maybe you need to add a ground wire being a plastic tank and are you sure the fuel pump is working. Do you have two fuel pumps if so make sure the in tank pump is working or you will burn out the high pressure pump. The sender in the tank provides ground to the guage check that you have about 8 volts pulsing going to the fuel sender with the key on.

I believe the newer in tank pump is a high pressure pump and you won`t need the one under the cab let us know what you figure out.
