Fuel Line Questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

72 Copper C-10 · 07-09-2015, 12:18 AM

Hello everyone,
I have a 72 k10 LWB that I am currently relocating the fuel tank. I have been searching for ways to do my fuel lines and I have come up with a few ideas. One idea that I particularly like is to buy fuel lines from a suburban and modify them to fit. I have looked at inline tube and they do not carry fuel lines for a 67-72 suburban, but they do have them for a 73 and up. I was wondering if the frames are similar between 72 and 73? I was also wondering if this could be an option, or is it a better idea to bend my own? any thoughts or opinions are greatly appreciated!

Thanks, John

You could modify a newer line but it would be easier to bend your own. You could use stainless for a longer lasting line. If you go this rout you could replicate the old line and add bends as needed. The downside would be the flared ends if you do not have the proper tools. If you are on a tight budget you could buy the longest lines you can find and connect them together. If you use an existing inline tube line you would have to be real careful when re bending it or trying to straighten bends.

Do you have the tools & skills to bend & flare your own? That is the best option. Nickle/Copper alloy line is more expensive than steel but is extremely easy to work with. You can easily bend it by hand.

Dont use rubber gas lines

Really, you need very minimal knowledge to make your own fuel lines, and it is much cheaper. The runs are relatively straight, and your flares don't need to be great to get a good seal with the rubber line and clamps it needs to run to the fuel pump and tank.

Best of luck with your decision.
