I want the drainplug and fuel level to be something special on this tank. The fuel level can be checked by an external transparant fuel hose. Mounted using titanium banjo bolts and a banjo to 6mm hose conversion fitting. Cool looks and an old school method of acting as your fuel reserve light ;).

The bleed valve to make sure the tank will never have issues with a vacuum is mounted with the same solution on top of the tank, with the hose going to a one way valve. Making sure the tank can only suck in air, but not expel fuel gasses.

And the drain plug is a titanium bolt that can be secured with lockingwire to the tank Located at the bank for easy draining.
