hi,i had the same problem,i couldnt buy the fuel pipe anywhere,dont sell it,so what i did was got some different pipe which was a bit bigger,i drilled some pilot holes into a piece of plywood,basically just a template hole for the new fuel pipe going into the tank because it has to be a tight fit so the fuel dosent leak out,once i got the correct drill size i drilled the fuel tank on the strimmer and fead through attached filter on and pulled back a half way into the tank,then what i had to do was attach another pipe on the outside and slide it into the new one,apresto it worked a treat,a bit of messing around but cured my problem,i think a good idea is to remove the fuel when not using and fill up just when you need it as i think it just perishes the pipe as before,hope this all helps,mick
