I have a hard time understanding how wise it is spending ~$120 dollars when you can make this gas transfer device for less than $60. It is way to simple to make and a real pleasure to use instead of pouring and spilling gas. If you need step-by-step instructions or pictures, just let me know, I'll work on it for you.
Anything I can do to help augment the cost of diesel and promote boondocking, makes me happy.
