Hi Lee

Thanks for the offer of parts, i'll pass on that as i'm in Austria and getting anything sent here since brexit is a total PIA. What I was thinking of using is something like this gentleman has in his video https://www.youtube.com/watch?v=sX5d4mYW3-Y he uses some quite fancy couplings and I was wondering if I could cobble up something a bit more simple. I've got fans and a radiator and was wondering if there are industry standard couplings hose etc.

Regards
Andrew
