Smog Pump to Manifold Air Tube Hose

Question, i'm looking for the following "smog hose". I bought a 1991 Z28, 5.7, Auto, I live in California, and I will keep the smog equipment. The hose that goes from the smog pump "air box" to the airtube on the driver side is gone. Does anyone sell that specific hose or do you just buy a hose long enough with the needed diameter?

Thank you.

I would just get a hose in the correct diameter, cut it to fit the length needed.

Re: Smog Pump to Manifold Air Tube Hose

The original hose was molded with bends to wrap around the back of the motor. It is no longer available new anywhere. You can probably find a good used one. But, as was suggested already, heater hose works fine too. The molded bends of the original are nice, but not necessary for it to fit and work.
