looking at how my lines are routed and comparing to the vacuum diagram, i thought i have a misrouted line, only picture i could find showing the nipples is here:



on my car the top most nipple going to the right is going to the valve just below it (EGR?) and the second one down is going to the nipple on the ypipe just next to the CRV hose (1" dia) connects to the CRV

now the way I read the diagram, the top most nipple should go to the y-pipe and the one under it, pointing left, should go to that valve (egr?) ???

i checked the lines on the other side of the uim and they run parallel to the 4 pipes.

i clipped the area from the diagram, on mine the "yellow" is coming from the top most nipple and going to egr valve, the "green with dots" is going from the nipple below it to the y-pipe, in the diagram the ypipe connection is above the egr connection

hope that kinda makes sense :/
