Post intake manifold install help!

[Geoman]

So I just finished cleaning, rebuilding, replacing the intake manifold, injectors, vacuum lines, ICV, AOS. Put it all back together, started her up and I see two gas leaks. One is definitely coming from a nut where gas is bubbling up through the threads (see pic). I never touched that nut, not even sure what it's for. Didn't see that happening before. The other likely leak is from the #1 intake gasket connection, and I made sure I placed that gasket down properly as it's orientation is different from the others. Torqued all the bolts to around 18 ft-lbs. The others are fine.

Suggestions as why the leaks and/or what to do?

Thanks. There's always something that gets ya!

HOLD ON....just ran it again for 15 minutes...no leaks at all from those two places. That's good, but I now have leaks from the two fuel lines! Must of stressed the old hoses when I was moving the injector rails out of the way. Well, time to replace them!
