Does anyone know where I can get a repair kit for the connector that has the blue tape on it? Did a smoke test and it’s leaking where the plastic line goes up into the connector.

That looks like it would work. I’m going to gently try and pull it apart. If it comes apart I’m going to try some black RTV and wanted a back up plan if that failed.

LMR sells a vacuum line repair kit. It comes with those connectors and that thin plastic line. I bought two over the years and they work great.

Dorman makes the thin hard plastic line as well. I beleive it's in the HELP! Aisle at your local parts store along with the vac line connectors.

I would assume this is the kit LMR sells

Good point and probably a cheaper option too.

That looks like what I got in my kit from LMR. I'm not sure the exact size but it was some of those connectors and some line (both hard line and rubber line). I'm pretty sure a lot of the vacuum stuff is generic.
