I have the tilton 3 chamber reservoir for brakes and clutch as many others do. The caps on the reservoir are open to atmosphere which I guess is ok for their intended purpose - race use only - as the brake fluid in race applications is changed often. For those of us that use this reservoir and don't plan on changing the fluid often, it would be nice to have a seal to prevent air getting into the fluid, and not create a vacuum (or at least too much vacuum).
I found a Dorman master cylinder gasket (Part number 42081) that fits quite well and does the job. $10 for 2 on amazon. I did have to remove the material on the underside of the stock cap. It took a makeshift mill with my drill press to remove the molded in ridge.
