No. Check your fuel pump relay and inertia switch.

I replaced the Fuel pump relay, EEC relay, and the inertia switch still with no luck. the funny thing is that the pumps on both tanks would turn on the night before but the next day they both stopped working. the fuel filter is clear so it has me thinking if the fuel lines are clogged.

Check the fuse in the panel under the hood. I had a wire get rubbed bare and short out my tanks and blew this fuse. I dropped both tanks and swapped switches before I thought to check here.
