Reply to "Do our intake gaskets ever really seal ???"

Steve - perhaps I am not following the test set up? you were testing your fuel injection connections with 30 psi for all the feed tubes? That air has to go somewhere so I am guessing it forced its way past your intake gasket which was probably fine. As Doug said, the intake is in vacuum. If your engine is pulling say 17 inches of Mercury, that is only about 8 psi of negative pressure on the intake gasket. I would be concerned you blew it out with that test. But then maybe I am not following the test rig completely. Also, if the fuel runners never really saw that pressure, is the tubing test valid? Lee
