HKS EVC6 vacuum lines...something doesn't seem right
 

Anyone know what's going on with this EVC6 vacuum hose arrangement on a greddy Z? I'm talking specifically how the left two ports are teed together. As a sanity check I compared with my G, which doesn't have them teed together - at least anywhere visible...and unfortunately I've never installed one and the installation manual is in braille...I feel something isn't right.

Wondering if this is a normal arrangement?

Thanks!

Also my G has the EVAP solenoid where this EVC unit is (if I recall correctly)... has the EVAP system been deleted on this Z, or is that the EVAP solenoid stuffed in front of the regulator?

I guess mine is similar to yours. Mine setup is like this (using your pic as a reference) the left hose goes into a vaccum distro block, the middle tube runs down to the wastegate (not sure top or bottom) but has a tee going to a vaccum distro block and then the one on the right goes to the other wastegate port.

Thanks, any other comments? Can I assume this arrangement is 'typical'?
