I just got the majority of my Greddy Profec-B boost controller installed and I kind of want to still use my pillar boost gauge if I can. Currently it is tapped into the hose running to the fuel pressue regulator, but I now have a new hose running into the cabin. Can I -T- off of that hose and go to the boost gauge? I think someone told me not to tap directly into that hose? Should I have 2 -T- connections on the fuel pressure regulator, one for the gauge, one for the controller? Or does it really matter?

Thanks

You can use the BOV hose. It isn't always a good idea to T off the fuel pressure lines. If it came undone for some reason you have some serious problems.
