Will do Sir, so first disconnect my fuel lines from the rail and pump the gas back into the tank?These sentences lead me to believe that there is 'junk' in your fuel tank. Initially, it clogged the filter then was likely replaced only to push more contaminates through the new one.
More testing can certainly be done to confirm but it is beginning to sound to me like the tank needs to come out.
Once it's out of the car, it needs to be worked over inside and out. My prediction is that you're going to find a fair amount of rust inside.
My next step would be this: Disconnect the fuel lines at the rail. Run extension hoses and pump all of that fuel into gas cans.
