i am putting the finishing touches on my goldber tiger 2 and the fuel tank is going to be a tight fit-the access panel is rather small as well. my question is-how do i set up a refueling line? is it as simple as adding another line to the tank and keeping it caped off when flying? a link to a web site with a diagram would be great or any other explanation would be great as well, thanks-Sean

The engine is exposed why not fill using the needle valve line? The simple two line tank....

ya know, its always the really simple stuff that gets by me! the more complicated the problem the easier it is to solve. Thanks Broken, this is clearly a case of the answer staring me in the face while i was trying to overengineer a solution.

There's more than one way to skin this cat, if you run a fuel filter you can pull the fuel line from the tank side of the filter and fuel that way with just a single clunk set up. If you have a fancy, cowled airplane, you can run two clunks and buy a fancy metal plug and metal ferrule assembly (Hangar 9 has a nice kit) to go through the side of the plane or the cowl. Great Planes sells a refueler valve assemble with a special nozzle also, but many are worried about complicating the fuel inlet process with that set up. If you are looking at extreme aerobatics, many pilots feel two clunks may interfer with proper fuel draw once the tank is getting toward the empty side. In that case, you can install a T in the line between the tank and the needle valve. You will need to either pinch the fuel line or close the needle valve to fuel and defuel with this set up. If your not sure. Go to Tower Hobbies, look up one of their Great Planes models similar to yours, then click on the manual and look through instructions and illustrations for other planes, until you find a set up that appeals best to you and your model.

I am on a K.I.S.S streak after many monthes in M.I.R.C.B.I.H.T.M.T.O.M.H mode..

K.I.S.S = Keep It Simple Stupid
M.I.R.C.B.I.H.T.M.T.O.M.H = Make It Really Complex Because I Have To Much Time On My Hands

Say what? Two clunks? The 3 line setups I run only use 1 clunk. The fueling line is a solid tube to one of the front corners of the tank. BTW, the fancy metal plug thing is commonly called a fuel dot.
I've been using the Dubro fueler on a couple planes for a while now. So far, they are fine.

I always have a hard time bending tuding around from the stopper down and to the front corner of the tank, then bending tubing up to the top for the vent, then getting all that tubing in to the tank when I install the stopper. So I use 2 clunks, it's easier for me, YMMV.

I used a Dubro fuel fitting for a little while, and had no problems with it, but I wasted the plane it was installed on, and I haven't put one on any of my other planes. I understand they always work well at first, but wear over time and start to leak air, but I've not seen it in person. I did find the odd size fuel nozzle annoying to use, espeically since I have a number of planes that don't have the fueler gizmo.

Twelve bucks for that darn fueler, plus you have to have the special end to use it. No thanks. I have a hard enough time keeping track of the little adapter I made to fill air retracts.

Although it does make the tank noiser, I think the two clunk setup is the best way to go. Not to mention, if you start having fuel problems, you can always switch your fuel line to the other clunk and rule out a split line in the tank, or keep flying for the day if you don't feel like pulling the tank out.

KISS..... words to live by.
