smog hose number

[Dale S.]

I have a smog pump hose that has the number, GM 389040X. Could someone tell me what this is for? I know it does not fit my C-2. Dale

GM #3890406 (PRODUCTION) and GM #3890404 (SERVICE) was used for L1966 and 1967 Corvettes with 327 and K-19. It is the bypass hose that goes between the mixture control valve and the carburetor base.

This hose was also used for some 1966-67 Chevrolet truck applications.

Thank you Joe, I thought that I had throw all that out in the early 70's, I guess I kept some it. I will post 3 other pieces that I found with it. You are once again a lifesaver. Dale
