Emissions removal related question
I've been following the attached picture as a guide for what to remove, but i've got a problem.I have a J-Spec s4 TII motor which i noticed where it says that the oil injector vacum lines hook up shows that there are atleast 4 different nipples on the UIM. On MY motor it only has 2 on that side?? Also the secondary fuel pressure regulator in the picture seems to have a vacum source which mine does not. Are there any guides such as this for the J-Spec version?
Any help is GREATLY appreciated.

What you've drawn there is basically correct except for the FPR. One of the weird little differences between Japanese and US engines is that the fuel systems run in the opposite direction. US cars feed the primary rail first, then the secondary, so the FPR is on the end of the secondary rail. The J-spec engine does this backwards (secondary then primary), so the FPR is on the primary rail. The line you've drawn from the LIM up to the UIM (which is just round in a circle!) should go from the LIM to the FRP.
Note there's only one FPR. What looks like an FPR on the secondary rail (but has no vac nipple) is the pulsation damper.
