I think I’ve finally made a rear over-the-frame section of new fuel line for the Chevelle I’m happy with. Above you can see, top to bottom, the original 5/16" line, my first piece in s teel (corners flattened out too much), and the second and third versions in aluminum.
After the first one (see my previous post) I got some aluminum tubing. I made a piece which was pretty close, and test-fit it. With some tweaking it fit properly, so I figured it would do. Now, I had filled this tubing with sand so prevent it flattening out much when bending on the premise of “why not” - I hadn’t accounted on the sand turning into sandstone in the bends, and 2/3 of it will not come out with any sort of coercion.
I made the third one tonight, lubricating the slidey bit of the bending tool excessively and shimming the slop in the die with some paper (needed .018" off the radius to properly support the sides of the tubing ). Going slow, this worked and it didn’t flatten out at all in the corners and it’s the most accurate one I’ve made yet.
This one will go on the car. I hope.
Next up will be mounting this in
place (easier said than done, as it has to snake up behind the crossmember, around the shock mount, around a body mount, over the flange on the frame, and tuck down on the inside of the frame rail in front of the rear wheel)
. After that, from there forward will be fashioned in a similar manner (I hope I have enough tubing left) and the two pieces joined with a union, wh
ich will be fine since it’s the suction side of the pump anyway.

Looks pretty good to me!
With the one that filled with sand, would filling it with water, letting it sit for a while, then blowing it out with compressed air work?

I doubt it. I put 100psi on one end of it (literally sealed to the air gun) and nothing happened. It’s very well plugged, I can’t imagine sand not making it worse.

Very nicely done! I chickened out when doing the lines for my Camaro and bought them off the shelf. When I got them is when I realized the the little piece of rubber line under the car joining the existing hard lines was factory and not yet another bodge by a previous owner.

I think that's why you typically use sugar or salt since they are water soluble.

Nice work! As for the sand, I think this is why people use salt instead. Even if it gets stuck, the salt will dissolve in water.

I was thinking water might help dissolve the chunks of sand, but that sounds pretty well fused!

Yeah, in hindsight something water-soluble would have been a good idea, but all I had handy was fine sand

Yeah in hindsight that is a good idea, but all I had a bunch of on-hand was fine sand, so yeah. Next time!

To quote the late Randy Pausch: "Experience is what you get when you didn't get what you wanted.". So, you got experience. And now you've got mad pipe bending skills. :P
