Among the wrought alloys 6061-T6511 is your best choice, for cost, ease of
machining, and availability, but for this application just about anything
would be acceptable. The -T6511 temper is most common but any variation
would be OK, such as plain old -T6. If you are digging through scrap piles
it's best to stay away from castings (such as 356 and other three digit
alloys) which tend to be somewhat porous, though not enough so that you'd
have to worry about leaks.

<hurstkr@growzone.com.au>
All,
I wish to construct my own vent fitting that fits on the rear of the fuel
tank just above the fuel filler hole in the tank.
What grade of stock aluminium (aluminum) do I ask for ?
Thanks
