VACUUM how much after should there be after 3hours.
 

I notices today when I replaced my Vac lines on the 4.2 that it still had Vacuum after sitting for 4 hours.

My 3.0 did not after sitting for an hour or so. Should it still have vacuum as well.

come on someone go yank their hoses off and see if it sucks in:) I'd do it for you.



(no I wouldn't)
