OK what is the best way to go? This is what I've got http://www.purefreedom.co.uk/pure-freedom-50-litre-trolley-with-2-drums-and-charger-p-289.html With this hose http://www.purefreedom.co.uk/30m-x-5mm-yellow-pvc-braided-hose-p-280.html and the Rectus 21 fittings on the pole. 13mm hose from pump. So do I cut the 13mm hose leaving enough to reconnect fit a couple of these http://www.purefreedom.co.uk/aluminium-male-hose-connector-with-13mm-hose-tail-p-570.html and use this between them http://www.purefreedom.co.uk/female-hose-connector-for-12-hose-with-valve-p-341.html Or shall I get an Aqua-dapter? Thanks for any help.
