so i got a new vacuum modulator for the c4 in the ol'pig (push-in) a few months ago and of course upon opening the box up this weekend its missing the stinkin o-ring
so my question is : is this o-ring made of some special kind of material or can i get away with just going and grabbing whatever they have that fits out of the o-ring assortment at the parts store ? any idea what size i need?
i'd just order a new modulator but it took almost 3weeks for the last one to arrive and blah blah blah
thanx

Re: vacuum modulator o-ring
Just take your modulator to the parts store & choose one that fills the groove width wise & has .005 to .008 protruding above the surface..
There is not a lot of oel pressure there & there is no movement at all... You will be fine.... lube it before installing.........Donnie
