what is this and its function?
what is this part and what exactly does it do... dont laugh but to me it looks like an egr valve but i doubt a 72 402bb has one being that old haha...its diaphragm operated off vacuum off the carb.. it runs smooth with it unhooked and sucking vacuum with it uncapped.. hook it back up you can see it function til its sucked shut and then it sounds like the motor is "cammed" i assume since its there it needs to be hooked up.. truck runs fine just curious to what it is
thanks tim
