Hello All :
Wondering if my year had a Air Pump and what ever comes with it .
Well Yes Smog City , whats needed License .
My 1980 928 US I believe has no Air Pump on it . I see no place to mount a Air Pump or a belt slot for it. I see one listed in the Porsche Manual that I thought covers the 1980 to 1982 models ?. My Motor number is M28/13 then underneath that number is number 8100038 . Car Build date is 8/79 .
Has a California EPA sticker under the hood so I gather then the car is a US model ?

Note: Car seems to have all the other stuff ? like Catalytic converter ( looks like 2 of them ? ) and a rear Muffler with single Exhaust , all looking Original.
The Car looks like it never had any Air Pump on it.

Thanks in advance if anyone knows if the 1980 US Model Requires a air Pump or not?
