If you measure the diameter of the pipe if its the small bore you may get some from a motor factors but it will be on a roll about 30m, which will cost about £ 20-30 if its standard garden type hose , just go to your local diy/garden centre and buy a roll, or try Argos , this will cost about £15 upwards, until you know the width of the pipe, its difficult to offer any real help.The micro bore on my trolley is 10mm outside edge to o/o aperture being 8mm, the garden hose is 12mm o/o to o/o apeture 10mm
