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.
