i picked up and sfmu off ebay and received it lastnight and i checkin it out. well i had to take it apart b/c i needed to know how it worked and i wanted to see what disc was in there and whatnot. so when i get it open it has that rubber diapharm and the large disc was stuck to the rubber so i was wondering if thats removable(i didn't want to tear it off and ruin it before i could use it) so would you add the other disc including the one thats attached? i didn't get the rest of the discs so i would have to order them from vortech and i also only got one spring so i'm not too sure what its even set up for at the moment. also on the outside theres the word boost casted in the metal and i wanted to know if that was supposed to have a screw for adjustment like the vaccum one?
TIA

the rubber should come off.

and the boost hole should have a allen screw in it. you dont need to mess with that hole. it regualates your max psi of fuel in boost.

Ok so i'm assuming that the disc is just stuck or stickin to the rubber part. and that alen screw would be something i could just order from a fastern company? maybe vortech?

does the hole not have anything in it? if so, i guess vortech should have one.

i think i know what you're talking about...mine is like that also... i think its supposed to be like that...there is a small allen head screw inside...then the vacuum has a bigger one on the outside...i was wondering this same question
