Thanks for the heads up.

Here is a picture of a new canister and
just above the "749" I ground a bit on the shaft (about an inch long where I ground). The shaft moves side to side and up and down a bit as the red rubber bellows sucks the shaft into the canister.
On one of my canisters the shaft (just above the "749") actually touched the top edge of the 3/4 inch diameter hole in the canister as the shaft was sucked into the canister. I relieved both canisters the same way as both canisters had the same issue.
The
picture was taken after I ground the top edge of the shaft so as you can see, it
does not take much grinding to get clearance required. I was thinking of grinding from left to right on the top edge of the shaft all the way to the first hole eliminating the step down on the shaft just after the first hole but that is not necessary.
It could be either top edge, bottom edge or both top and bottom edges of the shaft you might grind depending where you need more clearance.
I would install the canisters the correct way and then apply a vacuum to each and watch them as the shaft is sucked into the canister to make sure there are no issues. I actually have an extra vacuum pump I hot wired and connected to each canister but you can run a long rubber vacuum line (you can buy vacuum line by the 4-6 ft length very cheap from any auto parts store - get correct inside diameter) from your existing vacuum pump to each canister and hot wire your existing vacuum pump to get the same vacuum.
Correct installation would be for this canister installed on the passenger side with the "749" up right as you see it. Or for those in the mid west.......
