I do not see any evidence that i have a leak under the hood but it is pretty tight in there. does anyone have any suggestions?

 

How about under the rear of the car?
Maybe an injector o-ring is weaping some.

 

I have not seem any thing but i did notice since i posted that another string had the same problem with a 1999 S80t...he said that it was the fuel pump and he had to remove the back seat. so i am now trying to find out how to get the bottom of the back seat out

 

i am also not sure that is actually from the ac and not the back seat area

 

have fun with the seats.... you can get the bottom part out easily just by lifting it out however in order to see the two retaining rings holding in the two sides of the pump you will have to remove the upper parts too and them can be a pain in the butt... tech would be able to explain better then me since he helped me with mine..
