So a one metre length of the rubber hydroponic hose turned up this morning and I would have to say it looks and performs much the same as the original old rubber snorkel hoses. It is a tad stiff and wants to retain its shape on the coil, but that is only to be expected in mid-winter. I would suggest leaving it out in the sun for a while or soaking in some warm water. This hose could be a winner.
Still to trial are nitrile, silicon, and natural white rubber. Stay tuned!
Pic below shows early setup of rubber hose on a Pope mower. No formed bends at all, just straight pipe made to curve up from the carby connection. The main felt filter was housed down in that cylinder affair. The one on the end also had a felt filter of some description but was fairly basic. I've never seen one of the cap ends in the flesh so have no idea what they looked like.
