Max, I also have 70 LeMans. Going to 1/2 seams pointless because there is still 8inches of 3/8 pickup tube in the tank.You can pull only as much gas as a 3/8 tube will allow. The pickup tube is connected to the main fuel line, which is also 3/8, by a rubber gas line.The stock fuel pump also takes a 3/8 line. Are you building a faster motor that requires more fuel?A good working stock fuel pump will supply you with plenty of gas.
