Are you speaking of the fuel filter manager in the center of the engine in the back? If so it's common to leak. I replaced two o rings in it and was good. Labor intensive but easy. Will check back to give you more help.

This is located on the passenger side front of the engine. I know what your talking about but can't remember what the thing is for. I would just get a fuel pump gasket set for a '80's model 6.2L and use it.

Its the turbo oil drain tube, could get a gasket for it or if you have RTV you can use that.

I'm sorry. Omit my comment. I thought you said fuel leak for some reason.

Yea I did mine it wasn't to bad just a tight sqeeze. I got the gasket at the GM stealer for $9. Clean the crap out of the two surfaces. I undid the hose and took the plate off added some rtv and mounted the gasket so I didn't have to hold the gasket in place. But first check the ip to make sure the o-ring is good it will also run down to that area looking like the drain tube is leaking. The fuel pump gasket will work.
