vacuum hose coming off?

[tigerclaw]

I have an odd problem where I Park my bike and when next I ride it it runs out of fuel.... Then I check and the vacuum pipe is off....again. It seems to be that I Park The bike and it somehow coughs the vacuum pipe of the fuel tap? 2 questions.
1) What's with that?
2) the pipe is just pressed on, what clip is it supposed to have or should I wire it on?
Thanks

ps. .. I have just checked the bike after sitting for about 10 minutes. The pipe does seem to be under pressure now. ... When the bike is cold it's not

Hose should not be under any pressure, only negative pressure [vacuum]
Honda fit a 2 eared 3.5mm wire clip, [part is still available] but a turn of lock wire will suffice.

Clean the hose and stub in case rubber grease was used to fit the hose.

Great. Thanks

So I put the 2 eared clip on but I can see it has still moved... luckily it hasn't come off. I'm figuring when the bike stands after riding the block heatsinks and it creates positive pressure in the block. Does the block have a breather? If so where? I'm wondering if it's blocked

Get a slightly longer new piece of vac hose and use the clips. This should help
