Rear ride height without air shocks.

Looks like the problem I'm having with the air shocks comes from the driver side hose getting to close to the exhaust pipe. The pipe burnt a small hole into the hose. The shocks are a pair of Gabriel HiJackers part number 729706. Does anyone know of a place to get a replacement hose? I'm digging around the internet but there's a lot of different part numbers I'm seeing and I'm not sure which is compatible. Thanks.
