I'd hook the primary to the return line, and PUMP AND PUMP AND PUMP!!!! with the out banjo bolt loose on the secondary filter base. then once you get the car running off the return line, it'll blow junk out of the tank screen.
keep the fuel level above 1/2 tank, or you risk running out of fuel, because the return line sits about 4" above the bottom of the tank.
