chemie,
Here are a couple pics of the 10oz tank. It's hard to tell in the pic, but the outlet for the tank is about 1/4 taller than the slot in the fire wall for the hoses to pass thru. No big deal, going to put a little foam between the tank and firewall anyway, that will set the tank back from the firewall, so give more room for hose bend. Also, you can see some hardwood pieces that I have glued to the firewall and to F-2, and then shaped them. When I get the hatch all done, I'll post some more detail pics and info on what I did. Until then................
