Is it possible to have the clunk line inside the tank TOO flexible?
I decided to change the tygon clunk line in the tank for something a little more flexible and I’ve managed to track down some Viton tubing.
The supplier sent me two small samples for me to check out. One of the samples is quite flexible and the other VERY flexible.
My concern is that when the model is vertical, nose down, that the clunk line will fold back over itself and cut the fuel supply.
I would appreciate your views.
Thanks

I agree with your concern. I usually test the empty tank before installing to make sure it has the right amount of flop side to side, top to bottom and enough stiffness when held front down. Was the Tygon too stiff?

If you feel the line is too flexible, you can insert a section of solid tubing in the clunk line to prevent it from doubling back on itself. Some people solder a solid line to the clunk that extends near to the line where it comes out the back of the stopper. A short piece of flexible line here also prevents the clunk form falling too far forward as the solid line can only hinge around the rear part of the tank.

beats having to change a pesky fuel stopper... especially when you solder on babrbs

What is wrong with tygon tubing? I always use tygon inside the tank. Just make sure you replace it in one season or two.

Hey Guys
Thanks for your answers, I think I'll go with the one that's a little less flexible to stop it folding back on itself.

Nothing really wrong with Tygon (if you use the high-quality stuff that doesn't harden). OTOH, you can use Viton on the pickup line and be done with it...

Looked for an alternative, inexpensive solution and found ester based polyurethane, McMasterCarr #5549K44. Well into the second year now on this material, both inside and outside the tank. I recently took the tank apart to check the tubing and was assured that the choice was good.....the material is as flexible and strong as the day I installed it, some 6 gallons later, 12 ozs at a time. I've converted all my gasoline planes to the PolyU tubing
I will sell the Viton at 3$ per foot (+shipping) if anyone is interested, PM me please. Also have neoprene that I will sell at 0.40$ per foot (+shipping) if anyone is interested
