I'm doing the same and as far as i'm aware you need a pump(100psi) I'm going for a 100psi shurflow, a varistream( i think digital ones are the best) 100mtr hose and reel (microbore / minibore 6 or 8mm) maybe a strainer although i don't think you will need one and a leisure battery i would say around a 85ah one + the hose fittings.I'm not 100% sure what fittings you need but any supplier will tell you or i'm sure someone on here can help with them.
