I love my Topeak Joe Blow II floor pump that I've had for a few years...best pump I've used. Recently the air hose finally blew out.

Well that's fine, I thought to myself, I've always wanted to put a longer hose on there anyway so I could pump tires while the bike is up in the stand. So I head to an auto parts store and they sell me some fuel-line hose but it can only take 60lbs or so, and costs like $3/ft.

I figured I'll try it, so I head home with a 5 foot length and predictably, the hose balloons up from the pressure of pumping road tires to 110lbs. It is able to take it for a few days but then POW! Another blow out.

Back to the autoparts store...the only rubber hose with the same inside/outside dimensions they have that can take 120lbs is fuel injector line at $7/ft!! If I get only 4ft that is approaching the cost of another pump altogether! I don't mind spending some money but I think tossing a perfectly good pump is wasteful, especially since this hose material must be available somewhere. Topeak will sell me a hose but they only have 3.5foot lengths, and I'd really like to find a 5 maybe even 6 foot length.

So what on earth is the pump hose made of and where can I buy it in bulk? Is it PVC? I have a second pump that needs to have its hose replaced too. It has to be able to fit the fittings at the pump and head-end of the pump.
