vacuum source
as my vacuum source for my vacuum block for my boost gauge, BOV and boost reference for meth injection? I am obviously not using it for anything as I have removed my smog/air setup ages ago and just capped the vacuum line.
I am assuming the check valve will need removed?
Thanks
IF so anyone know where i can purchase one?
BTW if i use the one circled above do i need to remove check valve thing on it?
