Stupid question time again!

Should I put any form of sealant around the nipples for the fill and vent lines on my coke bottle? If so what stuff should I use? I have read that 'Seal All' can be used in the US but I am not sure if I can get it in the UK. What can I use that won't be attacked by the Kero?

Thanks

Automotive sealants should work ok ...

Even Seal All will become weak and develop small leaks after 80-90 flights. No big deal though, you will see it when fueling up. Take it out, seal and you good for another 80-90.

I have a 2 litre coke bottle in my Harpoon/Rookie. It's not sealed with anything, just done up at tight as I could get it by hand. It has been in action since February and I always leave it with whatever fuel was left from the last run and it hasn't leaked. When you think about it, coke can be pretty corrosive stuff as can any carbonated drink. CO2 is acidic and so the standard material for fizzy drink plastic bottles and caps need to be pretty inert.

Thanks guys,

Next question.

I have set up the tank with an orbit/Jetcat clunk. The clunk is at the bottom of the bottle. If I tip the bottle up the clunk falls to the lid really easily.

Do you just leave it like this? I am worried about the fuel line tying itself up!

Does anyone use a rigid tube in the clunk line or is it not necessary?

Thanks

I just used the regular tygon tube and have never had a problem with it. There isn't many times in flight that the plane experiences the type of force that will cause the clunk to move towards the cap.

Same here, I had that setup for nearly a hundred flights on my first ROO.

I used a coke bottle in my Hotspot, the best way to stop the clunk folding back on itself is to cut the "plastic pipe" half way down to the clunk and put a 4"-5" length of brass tube the line the put another short length of plastic pipe to the clunk. This will make it impossibl for the cluck to fold back on itself.
