Anyone have any ideas for a separate fueling line. I thought about just adding a "tee" in the fuel line, but I have been told that it will flood the carb.

I don't have room for a qwick fill kit but the fuel line on my OS46FX in my Magic is very hard to get to.

Any of you masters out there have any thoughts?

Mike

An old but simple solution is to add a third line that you plug when flying. The tee will most likely give you some flooding problems.
No room for a fuel dot?

Have you considered using the Kwik-fill fuel valve, if I am not mistaking I believe it offers a valve that will divert fuel to the tank and not the carb.

Edit in:

OOOPS Sorry I guess I missed the statement,
I had just asked the moderator to remove this post in which he did and here I go putting the post back. *fatigue sets in*

AV8TOR,

I think that is the best idea. I was trying not to have to take the tank out (only because I'm lazy), but a third line is the best solution.

Thanks.

If I'm using fuel dots, what is the best way to set that up? Since the engine is completely in the cowl, I also need to have a way to see that the tank is full without unhooking the line from the muffler.

Thanks,

Herb

I have a couple of planes setup like this. you pop three holes in the tank stopper one goes to your vent, second goes to your carb, IE has the clunk and the third is your fill line. The way I do it is I barely stick the fill tube in the tank so that the tubing do not get tangled together inside the tank. and the way I de-fuel is through the fill tube by putting the plane on its nose. Only the carb tube has the clunk.

Randy

Blackie, where do you usually put the fuel line tube when in flight... just let it hang with the stopper on it? Do you attach this to the fuse some how to keep fuel from coming out? Thanks!

EDIT: P.S. How far in did you put the fuel fill line's steel tubing into the tank?

A three line fuel system can be accomplished by drilling the third hole in the tank stopper. Use a brass tube on all three lines. Attach one end of some fuel line to one of the brass tubes and the other end of the fuel line to the clunk. Bend one of the brass tubes up for vent and bend the last brass tube down. Attach one end of some fuel line to the brass tube you bent down and the other end of the fuel line to a fuel filler dot, which should be attached to your cowl or fuselage. Attach one end of some fuel line to the brass tube you bent upward and the other end to the pressure fitting on the muffler. Lastly, attach some fuel line to the brass tube which has the clunk and the other end of the fuel line to the carb. When you defuel your plane, you do not have to set it on its nose nor will any lines get tangled in your tank. With a fuel filler dot, you will not have fuel lines hanging out either. It is a very clean installation. Good luck and happy flying.

Thanks for the help. It all seems so easy now!

There still seems to be the open question of knowing when the tank is full? Wait for fuel to spill out the muffler or time how long it takes or other solution?

I just use an "overflow catch bottle". I bought a small plastic bottle and drilled a hole in the cap so I could add a fitting for some fuel tube. Then when I fuel, I take the fuel (pressure) line off of the muffler and put it on the bottle.

Hit the pump switch and turn it off when you see fuel running into the bottle. i.e. tank full. No fuss, no muss, no mess. And then I can put the used fuel back in the can.

This would work the same with a fuel dot 3rd line or Kwik fill or whatever way you set it up.

Mike

Mike,

Yes, I do the same thing but if your muffler is completely cowled, it doesn't work that way.

I seemed to have forgotten about that when I said it was "seemed so simple." Thanks for asking the question, Topshelf. I would like to know as well.

Herb

My favorite solution to the problem of hard to get at fuel lines is to remove the needle valve from the engine and put it somewhere that makes it easy to get at.

Topshelf,

Ahhhhh, I see where that would be a problem. I guess you'd have to wait for it to spill out of the exhaust. You could use a larger piece of tubing to slip over the pipe and let it flow into a catch bottle or can.

The timing thing works pretty good, but you'd have to have some idea how full it was to begin with.

Oh well, another great mystery of the hobby!

MHawker,

I used the timer method on my AT-6 but I was just never very confident it was full. To fuel, I had to completely drain so I had a known starting point then start fueling and timing.

If your muffler is cowled such that you cannot get to the muffler pressure line, just fuel it until it comes out the muffler. If you are careful, you will only lose a teaspoon or two of fuel. Be kind to your fellow flyers and put a rag or paper towel under the muffler to catch the overflow. Glow fuel will kill grass and makes a mess of blacktop.
