You'd need a stock El-Camino FI gas tank. They only came in the later year elco's 84- newer I think, with a 4.3L V6 TBI motor. You also need the sending unit assembly from the same. BUT you'll have to change the pump itself out to a higher pressure and volume one. Thats if you want to stay in tank, if you want to go external, there are dozens of choices. For the intank you run a Corvette Fuel filter/pressure regulator assembly, pretty cheap, I think around $55 or so. Ck out the LSX swap forum on here for more info and idea's. HTH
