When you get your new hose, buy some spiral rap from your local Electrical supplier and rap the hose with it or just the area where it normally splits (usually near the handle).
Spiral (spelling) rap is basically a hose that has been cut in a spyral (the same stuff that you use to neaten up your cables behind your TV.)
It strengthens the hose so it won't crush or kink.
Cheers
Happy pumping
