I bought an aerotype fuel filler and need to fit a breather to the 650 tank. Does anyone have a spare inline on I can fit to the breather pipe?
It would need to push into rubber hose which I will mount between the tank and a hole in top of steering stem nut cap thingy. Crofty

and they're all shit!
I've tried just about every one I can find on my Saxon and they all let fuel pass under braking.
In all fairness, I cant run my breather line vertically out of the tank, it has to go horizontal between the fuel tank and tank cover as I dont want to drill a hole in the lovely sculpted tank cover.
If you find a good one let me know.

After a lot of 'hot fuel' problems on my 1170R I fitted one of these;

A push on version is available;

Cost about £50 from memory. I ran the fuel breather from the top of the tank, over the top of the engine, down to the swinging arm pivot (like a 'U' bend) & up under the tail, where I fitted this valve.
It all worked brilliantly, & never had a problem with hot fuel blowing back past the original 'one way' valve. Here it is;

Don't bother with one, run the breather to a small catch tank in the front of your fairing via a fairly long route. The catch tank needs to be above the fuel tank and have the pipe to the bottom of the tank, when you brake any fuel is deposited into the tank and when you accelerate it is drawn back into the fuel tank.

go to a car breakers and get the brake servo pipe from a petrol car.
They have one way valve that is fuel vapour resistant
