track pump hose?

The hose on my track pump (Topeak Joe Blow Sport) has expired. At the
point where it customarily sits bent when put away, the hose has
cracked through, letting the air out.

My lbs can get a replacement hose-and-valve-head, but I'm quite happy
with the valve head I have.

So, anyone know a source of suitable hose? It looks like it's just
rubber hose, 10mm OD, 4mm ID. I'm sort of hoping for somewhere that
does 50p-per-metre 'cos they think it's just rubber hose, rather than
track-pump-specific 12 quid for less than a metre.

You could try a car parts shop and check out fuel hose. I got a couple of
short lengths ages ago, of ID to suit the two standard sizes of copper brake
pipe. Can't find them at the moment, so can't give measurements, but worth a
try.

Is half nearly the right answer (!).

Car parts shop furnished me with 'vacuum hose' (I think that's what he
called it), which was 9mm OD, 3mm ID and a bit softer than the pump
hose. Simply fitting this as is, it blows off the barb, because the
clamping collar is too large. However, add some turns of PVC tape
over the hose to bring its OD up to a tight fit inside the collar, and
I can get to 120psi with no sign of slippage (in normal use I stop at
100).

Thanks.

*The* man for this was always Francis Thurmer and his 'Hard to Find'
business selling small but essential cycling parts. Googling him
revealed that he may now be specialising in mudguard parts but I would
guess he still does all the other obscure parts including stuff to keep
track pumps going. See http://www.hardtofind.biz/index.html .
