1972 fuel line differences?

[Mike_The_Grad]

I am kinda stuck on something and hopefully someone can assist me.
I am replacing the fuel lines on my stock 1972 C/10 LWB with SBC350/TH350 and the tank in the cab. I just purchased a 2 piece set of replacement 3/8" main fuel lines for 1971-1972 Chevy C10/GMC C1500 8 Cyl. 2WD. And a 2 piece replacement set of 1/4" return lines because I have a 3-port mechanical fuel pump.
The 1/4' return lines fit perfectly. The 3/8" line from the tank to beneath the cab fits perfectly. The 3/8" line that runs along the frame rail is nowhere close to the 3/8" line I pulled out of my truck. See pix. What am I missing? I'm assuming that there are different fuel lines for the different C10 models for the 1972 production year.
I understand that there are different sizes/lengths/routing for the different chassis (K-series,P-series,10,20,30 series) And different engine sizes (i6,Small Block, Big Block)
I'm only referring to 1972 C10 with Small Block V8.

I can't really help you, but I can say that I have the same setup, and ordered a set of stainless gas lines from LMC, which look like the same set of lines you have there, and I have that nice stainless piece you mention hanging in my barn right now for decoration. As you say, it was nowhere near what the original piece was like, and I couldn't figure any way to make it work. I ended up making my own line for that section.

Dfwright - well at least I know I'm not the only person with this issue.
I appreciate the sentiment. Lol. I am leaning towards just putting it back in. Only because my tube bending skills are subpar. I bent my own line from the pump to the carb. Cost me $5 for a double flared length of pipe with the nuts on it. I used a wire coat hangar as a template, I have a very nice bender I borrowed from a friend whose family business recalibrates gauges. 3 hours later, I had it in the truck and I was short by an inch. so I bent another one and I got it to connect, but it looked horrible. Lol. The line that needed replacing was the 1/4" return line. And that one fit perfectly. Interestingly though is that It's listed as being for a 1971-72 3/4 ton 2x4 with V8. LOL!
