This is a working unit! As you can see from the photo the gauge that tells you how much gas you have left(which is only good the last second before your tank goes dry) was dented so it only reads 250 instead of 500 on a full tank. The white back plate is pushed in a bit which blocks the needle from climbing any higher. This doesn't effect function of the unit and can probably be fixed if you have the know how or even care. They sell new for close to eighty dollars, I'll take $45 including shipping.
