Hi Neil,

I borrowed mine from a fellow flyer but I know he bought them in a HS here in the Netherlands. BTW the guy who runs the shop has been the dutch champion model aerobatics for a couple a years in a row. He's the one who recommends them apparently.

In any case I did a google search and found [link=http://www.jperkinsdistribution.co.uk/list.php?subcat=63&cat=Fuelling%20accessories&Navm ain=Field%20equipment]this[/link] site. It's the 8th one on the list (part number 5508085).

The filt sucks full of fuel and there is actually a small reservoir under the filt so it has a small buffer. Seems to work sofar.....

Good luck....

Johan

Correction. I see the correct English is actually FELT clunk (not filt). Also on the website they seem to be aimed at petrol flyers but don't see why they shouldn't work with Glow....
