How the hell am I supposed to drive past gas stations with only an 11.1 gal tank?

Yeah. Probably a dumb question. I want to increase my fuel capacity so I can go further without stopping. As is it, I can drive just about as far as my 11mpg Yukon makes it before IT runs out of fuel. What's the fun in that? Anyone have any thoughts?

Flame away.


And yes, my yukon really does only get 11mpg. The Yaris averages me out to mid 20's though.
