Gas Gauge Trouble

K, my Gas Gauge won't work, here is a pic of how it's wired up. The Gauge is brand new, is it wired correctly, the instructions weren't in it when I got the Gauge and I didn't worry because it seamed straight forward, any help would be greatly apreciated not having a workin gas gauge is really anoying, thanks.
