Getting ready to replace a few gaskets, got a Doorman intake manifold gasket kit from rock auto today. The kit included a little oring. Anyone know where it goes? I'm sure I'll figure it out when I start tearing parts off, but would be nice to know ahead of time.
95 5.2L Gonna try to include a pic, it's in the bag with the tb gasket.

 

Maybe for the little steel tube for the heater return line?

 

 

thanks!

 

Lol beat me to it
