trick flow intake vacuum line question

On the back of the stock intake is the one line for the pcv valve and the other has a splitter where one line goes to the vacuum junction and the other to the fuel regulator. I eliminated the splitter and tee'd the line from the vacuum junction into the line between the intake and fuel pressure regulator. These two lines were going to the same place at the back of the intake anyways. My question is, is this ok to do or no? Also i need to check all my vacuum sources, i have to get a gauge, and i have no idea where to start. Do i need to check every line off the intake and everything else? Any help would be appreciated.
