Crownvicman289 posted a simple guide on how to get rid of all unneccessary vacuum lines on your JDM 4AGZE;
"Fuel pressure regulator and air bypass valve should share a vacuum line (teed) that leads directly to the nipple adjacent to the inlet on the intake "manifold". The nipple will be on the JDM driver's side of said inlet. MAP sensor gets its own line that leads to a small, plastic thing screwed into the bottom USDM driver's side of the intake "manifold". Supercharger has a few vacuum lines (vents) that all tee together and lead to one end of the red VSV. The other end of the VSV leads to the inlet pipe just in front of the throttle body. Take all your extra VSV's and steel and rubber vacuum lines and throw them away, no needy. Enjoy a nice, uncluttered engine bay. BTW this also successfully accomplishes the ABV mod."
