I sorted my leaking fuel tap with a quick stop to the engineering supply shop.
I got a nice little s/s valve with teflon seals that will last for ever, some fittings and nipples and made up a little bracket to hold it on the right hand side inside of the frame.
A new fuel tap was $90NZD and all the bits and the hose cost me $20NZD......................Pretty good if you ask me!!
