Direct port is on but some of the nozzles are a little loose. I tried red lock tight, but it didn't stick. What would be the best way to get the nozzles to seal to prevent any vacuum leaks? Black RTV? More lock tight? The red stuff I had was a little old, so maybe it went bad? I don't know. What should I do? Tap out the holes a little more and just screw them in farther?

 

Teflon tape maybe ?
