Thanks Jack,
I often get strange looks from the staff of hardware stores because I am trying to explain my use for a certain part, which goes against all their preconceptions, like adapting a common plumbing fitting to use on a lawnmower. It is a foreign idea to some people, and I have even had staff tell me that I will void all warranty by using a part for something it was not specifically designed to do.
Perhaps a better air filter to suit the Bendix would be these ones, especially the one that has the rubber ends. They can be made to fit snugly into the old Bendix canister to produce a tight seal. The neck on these filters also allows for the necessary air flow at the base of the old Bendix canisters.
