Gas Tank: Tank is not rusted, has a plastic liner. The rust is likely from the old fuel pump. Siphon out fuel, wipe down gas tank. Since the fuel pump sender was replaced, I would at least try to use it.
Fuel Filter: change it out again with new one.
Fuel Injectors: Install new set, FIC or Accel are the best value & proven performance. Price range $650~$725 (parts only)
Tires: Replace with new. Save your old ones, as you may be able to sell them as originals to NCRS enthusiast.

Be on the lookout for rodent damage. Mice really like the LT5 Hotel & will chew on the wiring under the intake plenum.

Cooling System: flush & renew coolant

Engine Oil: Filter & oil change, 100% synthetic, Mobil 1, Valvoline, or any major brand, since you are making ready for sale.
