fuel tank breather pipe size. (small one)

[Hobbit]

Turns out mine has been blocked off for the passed couple of years . Possibly leading to my tank pressurising, pissing fuel out the filler and causing me to have trouble turning left....

Just after the size so I can bodge something together tonight as I have a track day tomorrow. Quick search says 5mm. Csn anyone confirm this?

100 forum points to the first answer.

4.5mm

i very much doubt blanking that one off will give you problems, mine never have

large breather hose going to the filler neck can give the problems you described tho
