Where can I buy vacuum hose?

[Katman]

Irrelevant, far more important in context is how does that compare with a humans ability to generate a vacuum.

I just checked by sucking on the unreinforced rubber hoses on my vacuum gauges.

I got to 20 inches before it started hurting my tongue.

Which is not a lot of use if it blocks itself off and fails to pass that vacuum along the line. One example of that is using random plastic hose for vacing down composite parts in bags... not only does it need to be vac hose for any sort of consistently, but it also needs to be resistant to the resin fumes.

How much vacuum do you think it takes to open a fuel tap?

I'm not sure why you keep asking generic questions with no answer. I'm also not sure why you'd do a half arsed job instead of just doing it the right way, but I guess that's the Kiwi way... and probably some of the reason bike shops are going out of business and nobody cares.

just nick it off your Mums vacuum cleaner.

According to a figure that I read somewhere, on my bike when the engine is on a vacuum of 3cc worth of air is generated.

Does that help you guys argue? :P

Believe me, I'm far from going out of business.

What customers don't like is someone bullshitting them that only a NASA approved product will do the job when in actual fact the problem can be quite adequately solved far more easily and conveniently.

I agree with that, and I do accept that some pragmatism should always be used. However I do also think you should try to use a suitable product if one is available at negligible cost. To me this is no different to scummy recommending any old piece of hose for a brake reservoir last week... why would you not use a hose actually rated for that? It's cheap and easy to get, I don't see why you'd go about making life harder for yourself.

which reminds me I must touch you up for some of that proper stuff.
