Okay, here’s the final installment in this saga. The short version is that Inline Tube DOES NOT have the correct fuel return line for the Jetfire. They simply make a 1/4 inch duplicate of the main 5/16 inch fuel line and call it the return line.
I went my rounds with the customer service guy at Inline Tube when he told me that they could not find the correct patterns for the ’62 Jetfire fuel lines and that what they sent me was correct according to their records. When I asked for my money back, he said they wouldn’t do that. Bad move. I let him have it as what they had sent me was absolutely not correct and I wasn’t about to pay an extra 60-70 bucks to ship him my correct and original fuel lines, especially when they didn’t inspire confidence in me that they could do the job right. Well, he got his supervisor on the phone and this guy seemed more knowledgeable and was aware that the Cutlass and Jetfire main fuel line is identical. He got involved and called me back a couple hours later. He’d figured it out. They had sent me fuel lines for a JETSTAR, not a JETFIRE. Wow. Anyway, he said they had the correct patterns and would make them and send them to me, no extra charge.
Okay, well I got them and the main line was correct, but the return line was not, as I indicated. The original return line matches the main line up until under the front wheel well where they enter the engine compartment in different places, resulting in a different length and bend at the engine end of the lines. I was tired of dealing with these guys, so my friend took what they had sent me and bent it to match my original return line, cutting it off to length. So, there you go. Beware if you try to buy Jetfire fuel lines from Inline Tube.
