You've checked and double-checked
installation of the pump in the hanger assembly, so it's time to
reinstall the hanger assembly in the fuel tank.
1. Replace the hanger
assembly, making sure it's positioned exactly as before. Take care
not to allow dirt or water to enter the tank, because contaminates
will cause premature pump failure.
2. Install the new seal in the
tank channel or the hanger lip. Fasten with screws tightened to
the manufacturer's specifications. Or, hand-tighten the lock ring
and snug it down by tapping with a non-ferrous punch.Don't use
gasket sealant!
3. To run the pump, position the tank so you can
connect fuel lines and electrical wiring. Make sure the tank holds
enough fuel to prevent the pump from running dry! Reattach the
negative battery cable and switch the ignition on. You'll hear
the pump operate for a few seconds, then shut off. If not, disconnect
the battery again and review the installation from here on back.
4.
Everything checks out okay. Great! Install the filler neck, if
necessary; secure the tank straps; remove the jack stands and lower
the vehicle. Refill tank with fresh fuel, or the filtered clean
fuel you drained from the tank. Final Testing the Fuel Pump Replacement. The vehicle may hesitate to start while the fuel system refills
and pressurizes. You may need to switch the ignition on and off
several times. Some ECMs shut down the pump in a few seconds if
the engine hasn't started. FINAL CAUTION: Inspect for fuel leaks, especially at the
tank connections and from the tank seams. Road-test vehicle from curb idle to highway speeds
