on the 5.3 intake manifold


off of the brake booster, the vacum hose goes to the back of the intake manifold into a "barb" like fitting (its plastic and you can spin it by hand)




on the L92 intake manifold


the back of the intake manifold, where i need the vacuum hose to go its like a plastic plug, that you can spin by hand....






The problem is i need to put the plastic fitting from the 5.3 on to my new intake manifold to hook up that vacuum line, but how in the hell do you get them off? You can spin them by hand but they never loosen or anything?????


Any ideas????????????????????????????????????????????? ???????????






Thanks

Mike
