Was there a service and/or replacement time/mileage on these canisters? Thanks. Ed

GM #17063011 is NOT the originally installed vacuum canister for your car. It's a replacement that occurred after 1983. The original canister for your application was GM #7028129. It was discontinued from SERVICE in August, 1971 and several other supercessive part numbers were used before they got to the 17063011..

The GM #17056582 is another replacement for your application, so that part will SERVICE your application just fine.

The only difference in I see on the charcoal canisters is they added another hose every few years so a later part will need lots of rubber caps to plug the unused holes.

You better double check that number. I show GM #7029131 to be a carburetor lever and NOT a charcoal canister.

GM #7028131 was originally used for some non-Chevrolet 1971 GM applications. As far as Chevrolet goes, it was used for all 1974 with 8 cylinder engines and some limited use during 1975-77. As far as Corvettes go, it's the canister used in PRODUCTION for all 1974-77 models.

The one on my 71 has the numbers 7030541 and 125 on it. No idea if it is original, but it has been on the car long enough that it had paint overspray from previous repaint which probably occurred 20 or more years ago.

If it's a very late 71 I could see where the 7030541 might have been the originally installed canister. Otherwise, it's a replacement that occurred sometime after August, 1971 when the 7028129 was replaced, for SERVICE, by the 7030541.

Joe,

My car is 18294, so around 1st of June, 1971. It does not seem to quite match what you are saying.

Any idea what the 125 indicates? I was guessing it could be a date code???

I would say that June, 1971 would be late enough to have received the 7030541. I expect the "125" is a date code but I don't know how to interpret it.
