Few months back I posted some information on a hose I used to replace
original.  Mfg by Thermoid see hbdthermoid.com for a listing of hoses
available.  I used a general purpose hose 1.25" EPDM, I think it was
originally for farm duty with 150 working 300 psi burst pressure.  Heavier
wall than original and double ply reinforcement vs single
ply.  Disadvantage is it is heavier walled, which reduces some clearances
which may cause you to do slight rerouting.  Stuff looks bullet proof and
so far no problems.  In the midwest it was sold at Farm & Fleet or
Fleetfarm which are common.  Price was well below auto parts store and at
this point as good or better.
