More manifold questions

[Richard McDonel]

I have three exhaust manifolds, believed to be one each from a 240, a 260, and a 280. All have air-line fittings that have been crimped off somewhere in their history. Common practice on many cars from that era. But can anyone tell me if there were ever 240Zs that did not have air pumps? If I want my 1971 240 to be a quality restoration, should I be trying to find an old air pump and mounting hardware?

Thanks

All North American 240Zs had air pumps. So yes, a properly "restored" 240Z in North America will have an air pump.

For 1971 as Arne said - all North American 240Z's had Air-Pumps. But it wasn't always so....

Late 69 production cars and some very early 70 production cars sent to Canada did not have, nor were they required to have Air Pumps. For that matter they didn't have Gasoline Vapor Recovery systems either.

A few 69 production 240Z's imported into the US came though without the Gasoline Vapor Recovery systems - but could not be sold in California. California required Gasoline Vapor Recovery systems by 1970 Model Year.

The hard part of replacing the AirPump and it's connected parts - is finding an Air Injection Tube assembly - that you could have sent out to be re-plated, or finding a NOS one. Getting one out of an old exhaust manifold can be done - if you find enough of them to try. You might get one out of 20 out in useable condition.

Short of that - painting one in place or setting up your own plating process - is about the only alternatives.

FWIW,

Thanks for the clarification, Carl. Good info.

Thanks all. Interesting stuff. I guess I'll concentrate on getting a good, running car going, and worry about the air pump later. No use holding up the project for something that few seem to have in place anyway. We ain't putting it on the 18th fairway at Pebble Beach!
