The fuel Cell is indeed made for gas. These tanks are essentially made with this purpose in mind. Most people mount them in their trunk, but being as I don't have one, it will be in the hatch area..

The system will be completely sealed, and vented to the outside, so no worries on fumes. The tank has a filler cap on the top, and I'll simply have to pop the hatch to fill her up.

I'm just trying to figure out what pump I need...
