Gearbox breather pipe diameter

Hi all,

Anyone know the pipe diameter for the LT77 gearbox/axle breathers? Mine are in need of replacement. Cheers

6mm o/d
Rough rule of thumb is if the pipe is rigid or semi rigid all sizes quoted are outside diameter, if its flexible its quoted as inside diameter.
Only thing to watch is wall thickness but that wont really apply with 6mm o/d pipe.
Ebay is probably your best bet search for 6mm nylon pipe.
