Joe, Here are the other 3 hoses that were in that box. 1. Looks like 890441. these might be the last digits as there is a rub mark in front of the 890441. 2. This one has a smeared number. Looks like 9903385 or could be 9908885. 3. It is very faint, looks like 3890442 with maybe a TN after it. It does have the ridges in it. These may not even be GM I dont know. Again thank you for all your help. Dale

GM #3890441 is an AIR system hose applicable to 1966 Chevy II and Chevelle with 283 or 327. It is the pump outlet hose. GM #3890442 is applicable to 1966-67 Chevelle and 1967 Camaro with 283 and 327 except SHP 327. It is the right side pump outlet hose.
"9903385" or "9908885" are not Chevrolet part numbers. In fact, as far as I can tell, they never existed in the GM parts system, at all. Assuming that the first digit is really a "3" and not a "9", the only number that I can come up with that even remotely might be the one is GM #3903382. This was an AIR hose for some 1967 application, but I can't come up with just what application. It might be truck.In Appreciation of John Hinckley -
Re: smog pump hoses
Joe, thanks for the help. On the second one the last digit is definitly a 5 Probably 3903385 the more I look at it. It appears " G7 1 3903385 IX " It has a double white stripe the full length, with "780 K" pressed in the rubber in several places. It has the marks from the Whittek clamps on both ends. Thanks again for your help. DaleComment
