1991, smog pump?

[Fesser]

Anyone know for sure if a 91 Blazer with a 350 had a smog/air pump. I agreed to swap a trans out of one for a friend that just bought it from a tow yard. Looks like the bracket is there on the passenger side but there is no pump and no fittings on the exhaust manifolds for tubes. I am hoping by 91 they dropped the pump or he is going to be upside down in a hurry on this thing. Frank

Look on the emissions label on the rad support or air cleaner. It will have all the emissions equipment listed that came on the vehicle from the factory.

I've seen 91s with air pumps and with out.

Might wanna try the 73-91 blazer/suburban board.

Thanks. I will look for the label.
