oops!
time to order up some intake manifold gaskets and new seals for the tubes. You can get it back in there but you have a 99% (Winfred?) chance of a leak. I had a real hard time holding them in on mine when I did it but didnt pull them out cause I imagined the extra work that would probably have to transpire so I wiggled the pump for quite a while in order to NOT accidently unseat them.
