That is the ASR/ABS modulator valve "prime" pipe and there is I believe a bleeder valve at the modulator valve. I believe (unsure) but in an ABS/ASR event it sends excessive fluid back to the rear reservoir of the master cylinder. I don't have a '92 but I'm quite confident of it's function. Hose at master goes to a pipe I believe that connects at the modulator valve, I'm sure the hose is actually serviced also as part of the pipe.

I'm very sure it's different than an LT1 base car pipe/hose. A GM part # for it would be 10158070 the pipe, the hose only aspect of it would be 10208515.
