Can someone give me a site that I can buy Clunk fuel line? It needs to be very extremely flexible. The thin line that I got still does not cut it. it is going into a Compass 3D fuel tank

Thanks for the help.

I use regular line, after a day or two while soaked in fuel, it becomes flexible.

I use Sullivan #205 medium (3/32" ID) silicone fuel tubing in both the main & header tank. It's flexible and doesn't swell from the fuel.

Hayes clunk Line 4
Greetings all. I have found that the clunk fuel line (Hayes clunk Line 4' is bad or I am using it incorrectly. After my second flight, the helicopter would not stay running. Come to find out that the fuel line came apart inside the tank and turned into gelatin like consistency. I had given it to three of my friends to try out telling them that this is the best on the market but all three of them had the same issues. So we decided to replace it with other product that Align makes. I was told that I cannot store the helicopter UN-fuel with the Hayes clunk Line 4. Is that the deal?

Thanks

Clunk fuel line
Not saying it did not happen,you could have got a after market look alike or just some old stocccccck! but I have been useing Hays tanks and lines for well over 30 years use to be called Kraft, tanks and black line one piece tanks like alot off header tanks,I still use them in all my planks the first thing I do when I get a new plane is trash the tank and hardware --get a Hays and upgraded hardware,I would give Hays another chance its pretty good product-I am done Rev-Ike

I'd second (or third or whatever) the Hayes black neoprene. It does expand a bit when exposed to fuel, so cut the line a bit shorter than you think it should be. Also good idea to use a bit of tubing as reinforcing collar on the clunk & nipple.

Initially your fuel goes a blackish blue, but this is of no concern; the discolouration stops after half a dozen tanks.

Are you sure this passes the "so what" test?

My vote goes to the Hayes line. The best in the business.

It's a complex, costly, glow powered anti-gravity machine!

Clunk fuel line
Something also I forgot to mention is alot of guys use a transparent fuel line durbro- areotrend,and buy a couple 4 foot lengths of LARGE and cut 1/8 small collars of the large tubing and use them for miniature hose clamps at your fuel connections,I run medium Hays line on all clunks (fuel tank and header tank internal fuel lines)Prather on all the outside lines,also at the end of the day I fill the tanks to the rim and then drain them trying to push most of the exhaust gasses out of the tanks thats what really is hard on your internal fuel lines,some guys just fill again after there last flight and leave it full till the next time they fly,which is ok, as long as you dont have a leak in the car whoops!and last its not to hard to once a year pull the tank also header if you run one and wash them out and put all new lines in also clean muffler nipple out too that hole can get smaller gummed up and drive you nuts on tunning too!hope this imformation helps someone.Later Rev-Ike

There was a bad batch of Hayes not long ago. We got a bag of it too. However it's the best clunk line in the business by far.

I had a problem with Hayes fuel line. I cut it the right lenght and after one flight the main tank linke has streached it self about 10mm. and the header tank one about 6mm. So do you have to pre soak it before use? I'm going to try the align http://www.align.com.tw/shop/produc...roducts_id=2491 next to see if its better. It has a good inner dia.

Just make the line a bit shorter than a 'standard' line would be. It does stretch, and colour the fuel initially, but it's not a problem. If you are not sure how much allowance to make, just keep your eye on the clunk for the first few tanks.

No need to soak the Hayes just cut it 1/8 to 1/4" shorter and you'll be fine.I have not had any problems with this stuff.

I love the smell of nitro in the morning..
