does anyone know the dimensions of the hose that works the air seat on a 09 man is it 6mm or 8mm ta Iain i want to fit an air gun
if you buy the air gun with the adaptor in the kit, it will fit 
6mm
Here’s a TruckNet Top Tip for free:
Make sure the seat is well chocked up with timbers before cutting into that pipe.
That seat is 'kin heavy and it hurts when it drops and traps your hands in the frame.
And don’t expect the other fitters to help you, they’ll be too busy laughing at you.
Just what I’ve heard…
