Referring to the tubes on the right in the photo above--the bends at the top are are 5 inch radius bends. I'll look to see what I can find in a 90 degree bend. Also, we use a rubber filler hose to go to the gas cap. That way you have a little play to get things to line up properly. The longer the rubber hose, the easier it is to work with.
We don't have any extra stainless tubes right now. They are being used on a SOHC install
