EPDM cap for brake reservoir clutch outlet - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Long ago I separated the brake and clutch reservoirs and at the time I put a cheap rubber cap on the outlet from the brake reservoir. That plug since broke down due to the brake fluid and now leaks. The inner fender paint under the reservoir is already all peeled up from the leaky reservoir cover (just found that TSB today after 100k miles of being annoyed by it!) so I'm just looking to patch up the sources now.

I found plenty of posts saying an EPDM cap is what I need for the outlet but I can't find any sizes or part numbers I could look for. The closest I found was a suggestion that NAPA has them (is this it?). Does anyone have a part number I can look up and order or at least a size to search for? Failing that, what size is the hose so I can put a stub on with a bolt jammed in the end and hose clamp it?

Yes, that NAPA cap is the same one I used, #6601698

Thank you for the confirmation. The NAPA nearest me has terrible hours so I went looking elsewhere as well. The Dorman 02256 3/8" bypass cap (and 02253 multi-size pack) is also EPDM according to an email I just got back from Dorman tech support and safe for brake fluid contact. My local Autozone carries this brand (and is open later than 5:30) so I'm going to stop there tonight and pick some up along with a tiny hose clamp for good measure.
