1/4" aluminum tubing source?

[C5Engineer 1170]

I need to build a couple more fuel cap vents. My local Aviation aisle at Ace Hardware has always had that stuff. I called today and the said they had every size except 1/4" and the warehouse had shown that it was discontinued. Lots of places to get it online including grainger but shipping has been more than a couple feet of it at everyplace I tried to check out at. Any other ideas on a type of chain store that may carry it? I only need about a foot or two depending on how many times I have to start over to get a 90 bend I'm happy with.

Hey Joey!  I think I used brake line from the auto parts store. Good luck

Joey,  I pick up some aluminum stock at Lowes.   I haven't noticed about 1/4" al tube.    EDMO

I found a 5ft roll of pilot light line on Amazon for $9 with free shipping. Not sure of the wall thickness. If it's too thin I'm sure I can find something to use it for on a project.
