How about building your own? The one I built takes 3 minutes and 21 seconds to completely empty itself (2 1/2 gallons). It takes less than 2 minutes to fill my Bobcat XL with the associated pressure. You can substitute a blue 5 gal kero can if you want. Here is a list of parts.

Fuel Gan 2 1/2 gallons....$2.75 -----Walmart
Kavan Gas pump.............$21.95----Local Hobby Shop
On/Off switch..................$1.95------Radio Shack
Project Box for switch.....$1.79------Radio Shack
Wire and clips.................$2.50------Radio Shack
Scrap Aluminum and bolt.$1.00------Leftover stuff
Tubing.............................$2.50------Local Hobby Shop
Glass or Glow fuel fitting..$6.95-----Local Hobby Shop
Total $39.00 or so!!!

Saving $100.00 bucks doing it myself-------PRICELESS
