Start at the easiest spot - the connection near the pass-side of the TB.
There is a 4 to 6 line connector under the dash...but that (normally)
doesn't come apart or leaks.

Thanks for the response. Sounds like there are a bunch
of them in there. Are they mostly in the dash? Can you
tell me about where the pump is in the engine?
I'll poke around today/tomorrow and see if I can see
anything that might have come loose. Otherwise, I
guess I'll just have to have the dealer do it.
Thanks again!
