Fuel tank

[wadders]

hello everyone, Can someone tell me why there are 2 places on the fuel tank to put the fuel line in with the clunk? which one should you use the one in the middle or the outer one?? will it make a difference?

[Fixxxer]

Inner one makes replacing the clunk line more difficult, use the outer.

[Mr.Brown]

if you use the inner hole , the clunk will be able to reach all the corners

If you use a header tank, that don't matter.

If you use the outer one, then when you need to you can squeeze the tank out through the frame sides for maintenance, with a bit of cajolling and fairy liquid.

I've had problems with mine leaking from the central solid bung recently and took some excellent advice off this forum to put a bolt through it with some wide washers to squeeze it up tight in the hole and make a really good seal. Works a treat.

Well I thought the outer hole made more sense(for maintenance) but for some reason it starts to use my header tank when I still have about 1cm of fuel left in my main tank. Does anyone recommend a type of clunk to use? Like a fuel magnet? How ^do these work?

When it starts to drink the fuel from the header tank it's time for a big auto and landing mate

I used to use fuel magnets but they kept falling apart and clogging up my filter. Try the lynx heli innovations mother of all suckers. Lynx Heli Inovations M.O.A.S. Fuel Tank Clunk LX0090

Will it stop the "foaming" in the tank?

Foaming is caused by excessive vibrations; changing to a MOAS won't stop or change that.

Personally I prefer the OS bubbleless clunk. It will never degrade, either from being smashed around inside the tank, or from fuel degradation, it sucks up every last drop, and it's plenty heavy enough to move around properly (unlike the MOAS from what I've read from a few on here). They are a bit pricey, but they are truly "fit and forget".

cant fault the os bubbless i swaped mine out on the velo 90 only to try the fuel magnet but can deffo say the MOAS is sadly one of the worst ive tried perhaps it will work in a header tank

The OS bubbleless works a treat!!!!
