I'm in the middle of an engine replacement. The primary injector air bleeds are in good shape but the rubber o-rings are shot. Mazdatrix has the complete air bleed diffusers with o-rings installed. Who, besides the dealer, sells just the o-rings?

 

I do.

PM me.

 

You could go to any autozone/pep boys/napa and get generic o-rings.. Since both oil and gasoline are petroleum based, they *should* hold up.. I've even used generic o-rings in a brake caliper, and it's held up perfectly fine for a few months..
