I have a Trex 600N and was flying on Wednesday and on the 6th flight it leaned out and I tried to richen it up but it wouldn't. Opened up a quarter turn and nothing, it stayed the same. Took motor apart, O.S. 50 Hyper and everything seems ok. Fuel filter clean. Was told line inside tank is bad, it is Hays fuel line. Anyone ever have problem with it before?

The line grows, if it did it could hang up. I put the line in fuel the day before and trim the next day. If you have any sharp edges on any part you are putting the line on you could have cut it.

junk the hayes line and use some good silicon line.The hayes line is rubber and unsuitable for nitro fuel,it swells up and deteriorates.

did you mean un-suitable? I disagree

The intent of using hayes, is its flexibility. In helis like the raptor, the angle that the clunk line enters the tank makes it difficult for it to reach the top of the tank while inverted when using standard (stiff) silicone line.

Also, although the hayes swells and gets a little soft in nitro fuel, it stands up to exhaust fumes which is usually what kills clunk lines. Due to the fact that it does soften over time, it should be replaced every flying season or sooner.

How is your muffler pressure line?, if it is leaking, fuel pressure goes down and you end up in a lean situation.

Yes in meant unsuiatable.there are plenty of silicon fuel line that just as flexable.

+1 millon on the USE of Hayes been using it for 4 yrs and NEVER had a problem with it breaking down or anything else. I use a fuel magnet and just make sure I refill the tank right after flying to get the fumes out. Great clunk line!!! IMHO

Hays fuel line in tank
I replaced the line in the tank and header tank and it runs fine now. I even put the needle back to where I had it. The line seemed broken down like it wouldn't hold its shape. Is it possible that the line was collapsing like a worn vacuum line on a car? I bought and installed the lynx fuel line for the clunk, any opinions on this line? Thanks everyone for all your help. It is greatly appreciated.

The hayes line is neoprene rubber,it is not intended for use with nitro,it will deteriorate and get soft and swell up and come off the fitting unless you clamp it.It will get soft enough to colapse, i have seen it very mushy. The lynx clunk works great

Lynx line sucks. It is so thin it cracks after a few tanks. Seen to many autos due that Lynx line.

Been using Hayes line for years. Of course I don't expect it to last a year of use so I change them about 6-8 months. Just remember it enlarges a few mm after first soak so cut it 4-5mm shorter.

Best clunk line IMHO, is the stock Align. That's all I've been using and it has worked great . I have a whole package of the black stuff if anyone is interested. .

Hays fuel line in tank
I only ran about a gallon and a half of fuel when I put the Hays line in. How often should the line inside the tank be replaced? All the other lines are in good shape. I don't see any cracks or anything. I put them all on when I did the Hays line in the tank, so they were all new.

It is not intended to be submerged in fuel all the time,this is why it swells up and gets soft. Use a good silcon fuel line....

If you look under a chemical compatibilty chart they are both, (neoprene&silcone), deemed not for use with nitromethane, (severe effect not recommended for any use). The silcone also gets soft over time, so the choice is up to you. Not to mention the other chemicals in the fuel.

I had to do a hard auto yesterday with my Raptor from a stiff clunk line.

I am going to give the hays line a try.

MY QUESTION IS. Do you guys having success with this stuff use any kind of clamps or just leave it bare? If it gets soft it looks like a clamp would cut it. I usually cut off a very short piece if oversize line and slide it over to hold in place. What is the best method.
TIA Fred

Been using Hayes for years inside tank. Have never had to replace one due to deterioration. Have to replace the silicone tubing 2-3 times a season due to deterioration. I replace all tubing at the first of the year when I start flying.

After the Hayes swells and is checked to make sure the length is correct, you will be good to go all season.

I use the double line technique. I cut a 1/8" long piece of fuel tube, then place it on the end of a pair of needle nose pliers, then spread it apart. while your holding it open, push your clunk line inside, and pull both off together. This makes a double layer thick line at all your line connections. With the hayes doubled up, it will just barely fit through the grommet opening to the tank. It holds very well, I do this on all of my fuel lines
