Fueling without disconnecting lines??
Is there anything made that will allow you to fill your airplane with glo fuel without disconnecting the lines to the carb and muffler?
I saw this http://www3.towerhobbies.com/cgi-bin...&I=LXK135&P=ML
and wasn't sure if that's what it's for or how it works.
If there isn't anything, someone should invent something
Thanks.

RE: Fueling without disconnecting lines??
Already done and used quite extensively.
A three system consisting of a carb line, muffler vent line, and a filler line to the tank. You can also put a "T" fitting into carb line to act as a filler port to the tank. There are several ways to do what you've asked.

I would just install a three line system and use a plug for the filler connection. Those easy fueler valves can leak air over time and lean out your engine and cause problems.

Get a fuel Dot, about 6 bucks, that's all you need.

or these?? http://www.centralhobbies.com/Fuel/f...s/tetdots.html
If that's right, I'm guessing you use those with tees http://www3.towerhobbies.com/cgi-bin...&I=LXG846&P=ML and some extra fuel line, correct?
Thanks.

Here's a few diagrams to explain how a 3-line fuel dot system is set up.

With that system, when you fill, do you need to remove the muffler line to see when the tanks full?
Is what I'd need is a stopper for the tank with three lines, fuel line and a fuel dot to mount on the cowl?

Cappaj1,
You don't necessarily have to remove the muffler line to fill the tank. If the muffler is pointing down you can pump in fuel and when the tank is full the excess will flow out the muffler. It's very important that you do this on a muffler that points downward, otherwise the muffler will fill up with fuel.
For a three line system you need something to close the third fill line. Either a stopper or a fuel dot. On the B-25 review I just finished I used the stoppers that you listed above. Look at the review and you can see how I dealt with them. [link]http://www.rcuniverse.com/magazine/article_display.cfm?article_id=1011[/link] . Presonally, I prefer the fuel dots. They are quick and easy to set up, and foolproof to use.

I skimmed the article - really nice build and article by the way - to the section on the three line system. Two more questions:
1) On the OS Max 46AX muffler the exhaust outlet is facing down but the connection for the tank line is on top. Is this okay?
2) Am I on track with about what I'd need below?
Stopper with three holes, three bendable lines, two clunks, fuel line, two cowl mounted threaded fuel dots ( http://www.centralhobbies.com/Fuel/f...s/tetdots.html ) ?

RE: Fueling without disconnecting lines??
Also, how do these work (see photo of fuel dots below)?
After mounting on the fuselage, do you just pull the plug and insert a tube into the opening?
Is there any leaking while filling or are the connections pretty tight?
Also, any disadvantages to the three line fuel system?
Thanks in advance.

B) Pretty tight.
iii) Not that I can think of. You should find an unobtrusive spot on a scale model but for sport the sky is the limit. I go one step cheaper and just use a fuel line plug that plugs the end of a fill line that is loose inside the cowl and hangs down beside the end of the vent line (which I also plug for transport in my stationwagon). http://www3.towerhobbies.com/cgi-bin...&I=LXK138&P=ML Two for 95ΒΆ

RE: Fueling without disconnecting lines??
I have the 55 ax and I have the fueler you showed at the very top. I have had no problems with mine and I fill till I see fuel in the vent line, sometimes a little goes in the muffler but it does not cause a problem. Just before you see the fuel in the muffler line you will see air bubbles, that tells me that i am getting really close to full and that it is time to stop. I also found on my nexstar that if I lift the front up just 3 inches I get more fuel in but that would depend on where the vent line sits in the tank.
