brake master vacuum feed location
I am converting my 13B Cosmo to a 20B and I'm just wondering what everyone else does for brake master vacuum feed?
the 13B engine has to big vacuum lines on the lim and uim for the brake master. I have looked over my 20B and cant find much. I was thinking I might have drill the tap the uim or something like that.

the 20B cosmo had one of those fancy electro hydraulic boosters (like a 2000's BMW, the cosmo is very advanced for 1989), so there IS no vacuum line
on mine i just used one of the hose nipples in the rare of the intake with an adaptor to get it to the right size, it worked fine.
you can drill and tap too
