I totally agree with pHaestus, go with the Dubro RC fuel tank as an inline reservoir. You can find it at
http://www.towerhobbies.com for about $3 + cheap shipping, or find a Hobby store locally carring something like it. It takes about 10 minutes to build, and works like a dream. Seriously I wish I had discovered this back when I first took the plunge because this system is amazingly easy to fill/bleed/perform maintanence.
