Brief Description: Step 1; Pressure test fuel tanks
Start 6/8/16. Air pressure leak test tanks. Used best balloons I could find at local dime and dollar store that sells lots of helium balloon arrangements. Found leaks at fuel filler caps, at balloon and air filler attach hardware. Replaced and tightened hardware fittings at filler and balloon attachments, tightened fuel filler cap nut, spread small amount of grease on fille cap O-rings. Tanks hold air pressure for days of inflated balloons, balloons expand and contract day-to-night, vis-versa. Belive they are sealed, we'll see.
