I'm replacing my old rubber 5/16 main fuel line with 3/8 on my 63 Polara 500, 383 engine. I see Inline Tube has both stainless and OEM. What is closer to original? Are there advantages to one over the other? Stainless is $99 vs. $69. Thanks. - Jim Jim Altemose, Long Island, NY '63 Polara 500 (Max Wedge) '63 Polara 500 (383) '65 Belvedere I (Street Wedge) '71 Bronco
