Disco 2 Fuel cooler leak.

Thanks for the info guys. Nice to know these things in advance

@Intestinalworm - this is odd, I went and checked the clips I took off my cooler and looks like they were wider than yours. These are 7mm, and I've sat it next to the 5mm jubilee clips I replaced them with. I suppose they used whatever they got supplied with!

Measured width with vernier calipers - original clip (bought the Disco new). Still have the original clic-r clip on at the rear of the fuel cooler - assume it is the same width as I took off at the front? I know there have been incidents with aircraft where the maintenance techs used fasteners that they thought were close enough/good enough when they couldn't find the exact part (happened on nightshift at one facility in the UK because the parts store was closed - windscreen blew out in flight!).
