Wanted Smog pump and tower clamps for March 71 built car
 

Need a pump dated prior to 45th day of 1971,
seized or free doesn't matter also tower clamps 5/8 and 3/4" dated 3rd or 4th quarter of 1970.

Also looking for a 1971 Corvette Consumer Information pamphlet.

Thanks
James

I have one but it 153 day of 71

Smog pump hoses use 1-1/4" clamps. I have one that's restored that has DCM stamped on it. The DCM clamps were not dated. So it would be correct for your car. The other clamps I have dated for your time frame will be 1 and 1/16 in with dates of 1/70 (2 available) , 4/70 [2 available)

I also have a 1 3/16 inch clamp dated 1/71.

James would this be a 7801149 pump?

Sent a msg on the clamps...

TIM,

Yes a 149 pump
dated something like
30001S 300th day of 1970
00111S first day of 1971.
04511S 45th day of 1971.
Car was built beginning of March.

I have one somewhere in a box of smog parts, from memory it is either off a 71 or 72 Corvette, since it had the vette-specific diverter valve. I’ll see if I can find it to check the date code, may take a while though. It did spin freely and had some hoses and wittek clamps too.

Found it sooner than I’d imagined; unfortunately it’s dated a year too late..... sorry.

I checked my pumps, I have 30711S, 16991S and 17411S, sorry nothing closer.
