Does anyone know where to get this? Our LHS doesn't have any. I'm looking for the thin wire used to secure the Tygon line to the clunk inside the tank and to the back of the stopper assembly inside the tank.
Thanks!


Tony

Hi there!
Well, I did the job with a ty-rap.
Come to speak of it, I have had a conversation with a well known person (he imports Vario stuff in Holland) and I asked him if he had some fuel line for INside the gas tank.
Guess what he sayd: No don't use the tygon fuel-tubing, he sayd "I always use common silicone fuel tubing inthere, will keep nice and flexible"!!
I told him about the tubing swelling, but he insisted "I've done this for many years, and the clunk-line will be flexible".
Anybody???
Eric.

don't use silicone tubing with gasoline...unless you want a real mess on your hands or actually enjoy failures! It's not compatible. That's why you use the tygon tubing.

Sales must be slow or has a lot of inventory. Be polite and go see your small engine repair facilty, chain saws, blower's ect.Should have spools of it to select from.

Vario doesn't use Tygon in its gasser tanks, at least not the 4 gasser tanks I have bought from them. The stuff they use is red in colour and much harder than Tygon. It also gets harder and more brittle with age and is far inferior to Tygon. Needless to say, I won't use it apart from on my fueling container.

Securing fuel tube
Tony Instead of useing wire or clips ,If you cut 1/8th inch or 3mm piece of fuel tubing off the length, then feed the length through the 1/8th piece, fit the length over the nipple and slide the 1/8th piece over the fuel tube and nipple it will work everry time,
I have been using Tygon as a clunk tube for years without any problems

You can buy the spools of wire from companies such as Machine Mart or equivalent. Its not particularly expensive. there is also a special tool, again not expensive, to produce a nice, tight spiral finish to the wire.
The full size guys use it all the time for all sorts of applications from wiring screws to securing exhausts etc. You may be able to get some from a friendly pilot/engineer.

Sure, I know that silicone and gasoline don't go together.
But the guy who told me this has a LOT of expierience with rc heli's, And is the importer from Vario here. I just wanted it of my chest! (thought maybe there is somebody out there who uses it too)
And tygon is not that flexible. I do use tygon with weight added to the filtclunk.

Thanks for the replies guys.

I never thought about checking the local machine/repair shops for the annealed stainless wire. I know you can buy stainless at the hardware stores but didnt know if it is actually annealed or if it has to be specially treated to withstand the exposure to gasoline. I have also used the method of securing the line using another piece of line like Peter Rob suggested, but that was only with my glow stuff and silicone tubing. I wasnt sure how well that would work with Tygon line over time.

Speaking of the line itself, the line inside my tank is the pink kind which does get rigid over time. I didnt build my heli so I was just sticking with what was already in it. The line hardens to form a curve where the clunk is always at the bottom of the tank. Since this heli is strictly used for AP, having the clunk line like that really isnt much of a problem. I'm aware of the twist tools for the wire. Used them on my ultralight a few years ago to safety tie nuts/bolts. In this application, a good pair of locking needle nose pliers works well.

Thanks again for all the input. I really appreciate it!

I will stand corrected but aren't both arms supposed to be inside the "U" part of the clip.

Also a danger with these that if applied to close to the "barb" section of the fitting, it will actually cause so much tension on the tube that it will cut it and cause premature failure.

I don't use ties unless it is on a plain smooth tube. Plastic tye wraps seem to work fine for that. Wires cut the tube and spring clamps can be nasty to install.

Everybody does their own thing, you can't say whos right or wrong.

Ace, do you use the plastic zip-ties on the inside of the tank?

ba board If you had looked very carefully you might have noticed there are 2 sizes of clip both made the same way and both from the same supplier, they actually make 4 sizes, if you feel they have been made incorrectly I would recomend you get in touch with them and tell them of their mistake
In 8 years of using these clips I have never had a failure I supose if you were stupid enough to use the wrong size clip, one too small then yes you might cut through the tubing

Ace bird You are right in what you say, If your ties do not come off then they must be right

I actually didn't post in order to get snide comments. I made the observation that if applied wrongly, irrespective of size, they can cause premature failure. FACT.

I also said that I would stand corrected if I was wrong. Irrespective of who or how they are made, I was under the impression that both arms passed under the "U".

"because you disagree it don't make it wrong"

, I don't use anything!
Tom We found that using some tubing with Jet A1 it went hard and would not stay air tight you can understand now maybe why some of us use clips, the last thing you want is air in the system, you are correct with your statment that you have never had Tygon come off a fitting neither have I
