Brian,
That price is real high unless the hoses are really long. Without the length, one can only guess.
If you can locate a local Areoquip dealer, he can sell you both proper hose and reusable fittings that you can assemble yourself. And, If you buy those and hose goes bad again, all you will need is the rubber hose by the correct number.
