    FPR help

    I always use the search before i ask a ? but i couldn't find anything. I have the FPR that everyone has the 13101 or what ever it is from aeromotive. well my question is do i have to hook up the vacuum line to it? all the pics i see of everyone's the line is never connected??? if i connect the line wont my pressure go up when i give it gas? or is that what i want it to do is go up when i give it gas?

    thank for any help and sorry if its a repeat ?

    thats for when you want to use the boost reference thing. i don think the vacuum line would do anything

    The instructions don't tell you any thing about it. I thought that's what it was for but wasn't 100% sure. If i did connect it, is that what it would do? raise the pressure when it sees vacuum?

    Supposed to add one pound of fuel pressure for every pound of boost.
