do a search on here for snorkel you should find my home made jobbie which doesn't look too bad,in total the snorkel cost me aprox £30 (£18 for the top, £5 for the pipe and the rest went on rubber hose to connect it and other bits like clips and stuff) as for breathers you will need some 1/8th bsp swivel connectors the bolt into your axle and some nylon hose to run up to your snorkel from it. you will still have the problem of it being a petrol and it cutting out when it gets wet tho, for deep wading you need a doosel
