Does anyone no were I might get a 3 tank shut off??

I have had 2 tanks all the time and just added a third were the I/O use to be. But I can't seem to find a 3 tank selector, shut off. I find 2 tank ones all over the place.

Thanks for any help!!

maybey something in airplanes?
how about three seperate single selectors?

Thanks but I was tryoing to replace the one switch I have now to 1 with 3?? I just found one at west marine online but say out of stock, but they are to have some the 24 of may?? I guess I will have to call them and ask.
Thanks!! Anyone else no were I might get one if this does not pan out?

Well I found one at the West Marine in Pebody. But thats way to far for me!
So I called my West Marine in Hyannis and they can order me one that they have them in there warhouse (Online warhouse is out of stock) and have it for me in a few days. $29
