Every step forward is worth celebrating!!

When you put the inline filter in the fuel line, I suggest that you plumb in a tee with a small valve attached. Then, if you need to prime your vacuum tank, you have easy access to a fuel supply. No need to carry around a small, red plastic gas can.
Also, you use a small plastic Coke bottle to catch the gas from the outlet mentioned in the previous paragraph and pour the gas into the top of the vacuum tank.
Attached are a couple of pics of my setup under Justin, my '28 Canopy Express.
