There is a vendor that caters to PPC flyers who offers a glass tube (or similar) with a floating orange pill. It has brass 90's and looks like it would fit or adapt to the kitfox configuration. I have a friend that uses it on his trike which has fuel tanks that were fabricated from stainless steel trays that are used on steam tables like you would see in a cafeteria setup. Two trays with the seam tig welded makes a 7 gallon tank looking similar to our header tanks only bigger. I thought it was a pretty cool way to repurpose something for a totally different application. I will try to find the website and post it later.
