1.If the pump assembly is attached
with screws, note location and remove them. If it's held in place
by a locking ring, gently tap and loosen the ring using a non-ferrous
punch to avoid sparks. Inspect the lock ring and replace it if
damaged. Note location of fuel lines and electrical wiring.
2.Carefully
remove the pump assembly from the tank. It may include a fuel-level
sending unit, so bending the float might cause inaccurate fuel-gauge
readings. Match tank O-ring or gasket with new ones for right size,
then discard the old one.
3.Inspect the in-tank fuel strainer carefully. Look for clogging
by rust or dirt, slime from water in fuel. A contaminated fuel
tank must be cleaned--or replaced--before installing the pump.
4.Inspect electrical connectors for corrosion, hanger tubes and
sender unit for damage.If hanger assembly appears corroded
or damaged, replace the entire pump and hanger assembly.
