Brake reservoir relocation kit leaking…..

I have a brand new reservoir from rock auto and I am getting a leak in the relo block. I tried different o rings and still leak, Am I missing something? It seems tight enough.

It does not seem to be coming from the brass fittings. I did use teflon tape on those.

Do those o rings feel tight going in? It’s been a while so I can’t completely remember how it went together.

DOT 3 and DOT 4 are essential the same, only difference is the reported boiling point. Don't mix these with DOT 5 as it is silicone based and not compatible. Don't believe using DOT 4 is the issue.

Could it be that Im using Dot 4?
DOT3 and DOT4 fluids are compatible. DOT5 silicone brake fluid is where you'll run into compatibility issues. Are the o-rings getting damaged during the installation of the reservoir into the remote mounting block?

Can you get me several images of the orings installed in the reservoir adaptor block without the reservoir installed?
