1984 Jayco mini

I have a 1984 jayco mini 25 with a 7.5(460)in it. It has been in storage for the past 3 years and has not been started. It turns over and I do get spark. The problem is fuel. I am getting power when I jump the oil pressure switch and ground at the wires on the frame rail that go back to the tanks. My gauge does not work on either my front or rear so at first I thought it just may be as simple as a bad ground since the ground is used for fuel level as well as the pump but I wasnt that lucky.The tank switch is working, I can hear it. What are the odds of both fuel pumps being bad? If anyone has any ideas and can be of assistance it will be greatly appreciated. Thanks
