Here's a general replacement compressor hose kit: sears.com/craftsman-20-pc-compressor-accessory-kit/p-00916191000P?sellerId=SEARS
I don't think that will work, but Bon-Aire should be able to tell you if that could work as well. You can also try calling Sears PartsDirect at 1-800-366-PART to see if they can help.
This is a similar air compressor inflator, but it just went out of stock: sears.com/craftsman-12v-portable-inflator-w-digital-tire-pressure/p-02875114000P?rrec=true
If you want a smaller compressor instead: kmart.com/craftsman-cm-compressor/p-A071960227?sellerId=KMART
Sorry about that, but hopefully they can help!
