Vacum line reducers I feel stupid asking this, but I can't find anything for what I need. I am installing a boost gauge, boost refrenced FPR, snow meth kit, Hobbs switch, and procharger big red race BPV. It seems as tho everything has a diffrent size port. The boost line I think is 1/8", meth and FPR are going to take 1/4" line I believe. The Hobbs switch will have to be screwed into somthing with a 1/8" NPT. The the BPV is going to need somthing pretty big, not exactly sure with it.
So what I'm looking for is some recommendations on what to do here. I've read the bpv needs it's own source of vacum. So I was thinking coming straight off the Intake where the evap line hooks up. But that port is a good bit bigger than the port coming off the bpv. So how would I go
about reducing the vacum line size?
Another thing I have considered is making my own vacum manifold. I would drill and tap for 1/8" npt. But the smallest barbed fittings I can find with 1/8" npt threads is not going to be anywhere close to fitting the boost gauge, meth port, or fpr.
So what I would like to know is what is everyone doing to reduce vacum lines from say 3/8"-1/4"??

look into making your own or buying a vaccum block. I bought a 4 port fuel block from summit with a 3/8 NPT femal inlet and 4 1/4 NPT female outlets for around $12. Lowes has all the brass fittings you'll need for 1/8, 1/4 etc... hose barbs.

Yeah I'm building my own block. I went to autozone and looked at the fittings. I just don't like how "janky" they look. My friend said he can get me some push lock type
fittings(like ones in meth kits). I think I'm gonna try that before I resort to mix and matching from autozone.
