Is it the PCM4LESS kit?
The AN fittings don't need Teflon tape. They may not be tight enough. Take them apart again and check the threads, maybe some debris?

Just curious, on the cooler itself - did the fittings thread all the way down for you?
The fittings on the cooler didn't but I got them as far in as I could

Make sure you do not overtighten the AN fittings, you can damage the tapered seat and it will never seal tightly.

The cooler takes NPT fittings (National Pipe Thread) they are tapered so you will still see threads when it is tight.
