The PO did the vac line routing.
The line going from A to B doesn't actually do anything, is this OK?
The line from D goes up to point E which is the secondary injectors rail. Is this OK? I think somebody told me that port D should go to a metered port.
Vac port C is just capped off, should it be?
I do have the oil injectors tied into a port on the firewall side of the UIM.

I tried to trace the lines out on the drawing but nothing on my S5 T2 seemed to go to where it should be.

thanks

OK, I think I found the answer in an old post. I just had to keep switching the search terms around until I found it.

Line A-B ties to line D-E and then attaches to UIM vac port.
Port C attaches to port E.

Is this the engine that you are having a problem with?
the 4 oil injectors have no vacuum lines running to them.

Yep, same engine but I removed the oil injection vac lines to get a better pic of the other lines but they will be reinstalled.

I used this drawing for the vac line placement. I think I got it right, maybe?????

aside from the oil injectors without vacuum lines, everything else should be fine. as long as the secondary rails FPR gets a vac source from the manifold itll work.

A to B is suppose to be like that for the fuel injector air bleed. If i remember correctly from deleting my rats nest there should be another hose on the other side of the rear secondary that goes to one of the 3 vac ports on the back of the uim.

Like calpico said the fpr should have its own vac source from the manifold because im about 99% sure that D is supposed to be the air bleed for the primary injectors. If C is an available vac port i'd use that for the fpr and run a line from D up to the back of the uim to one of the other ports where the other air bleed goes to.
