"The ground. "

hahaha
Ground 1

I used a cheap valve cover filter with grommet from auto zone with grommet and a aluminum co2 tank for paintball. I welded on straight -10 fittings to the tank. It looks just like the moroso tank but about half the price.

pics?

honestly dont have it anymore. It was a few years ago. sorry. The cool thing about it was the sides are pretty thick so welding on the bottle is a sinch

the ground also

I am gonna be building a tank for a friends car here in a few weeks, well after I am done with the turbo manifold and intake manifold.

^^ some pretty big projects ahead of you... I hope you know what you're doing... for your friends motors sake...

interesting

any one have pics of a homemade setup
