How long are you guys making them? I just ask because of the shape of the tank. Makes getting it in all the corners impossible.

Clunk line

The clunk tank that comes with the 600N leaves a lot to be desired, the fuel nipple and clunk placement is not very efficient at all, if you are not an advanced pilot and or not the best at low altitude autos install a header tank as I have, its just good added insurance....Jim

Personally I like the tank design. All I know about it though is I can fly pretty hard "3d" right down to the last few drops and my engine never leans out. No header tank or fuel magnet for me by the way.

As for clunk line length I think as long as the clunk isn't so close to the back of the tank that the back of the tank is restricting fuel flow and the clunk moves freely to the top of the tank it's going to work fine. I recently changed the stock clunk line out for Hayes line because of all the paranoia about the stock fuel line around here. I figured why not, easy and cheap to do. I did run the stock line for nearly 9 hours of flight time and when I took it out to replace it, it still looked fine but I agree aftermarket fuel line will be more reliable.

There is a very fine line between "hobby" and "mental illness."

I tell ya I like the small fuel line that comes with the kit. Nice and flexible. Will it last long, probly not but it sure works well. Wish I had some more. Looks like the Hayes would be so stiff it would not lay in the extremes of the tank. Anyway I agree that the stock configuration seems to work fine without a header tank. Now I said it so I am assured a forced auto on the next flight.

If you are going with the Hay's clunk line, soak the line in fuel for an hour or so before you cut it to length. It will stretch quite a bit when sitting in fuel so if you don't take that into consideration before you install it, it will be to long and get stuck at the back of the tank.

Ask me how I know!
