It appears the nipple in the LIM right next to the injectors for the oil metering system goes somewhere to the fuel rail according to the FSM but I dont have a nipple on the fuel rail for a hose, plus there is another line from the rats nest that goes somewhere and I have no idea where it goes. I appreciate the help-

you will see two nipples in the pic-

holy ******* huge pic batman. Sorry guyths

 

just scroll past my thumb to the right slightly, you will see them

 

That goes from there to the upper intake manifold. It is the vacuum line for those primary injector air bleed.

 

After hours of scrolling to the left I saw the nipples you were talking about. THe one that kinda angles off to the right (standing on the drivers side) goes to the fpr, I cant remember the other i believe it goes to one of the nipples on the firewall side of the UIM

try this

 

The angled one goes to a hardline on the vacuum lines and to the solenoid for the FPR.

The nipple b/t the two oil injectors feeds what is called bleed air to the PRIMARY fuel injectors diffusers. That nipple gets fed metered air from the rear of the intake manifold. ON the back of the manifold are three or four nipple one above the other. A hose connected to the top nipple back there feeds that primary air bleed nipple b/t the oil injectors.

 

just FYI, most people would rather see a smaller pic (as I'm sure you've realized) with the location in question circled in red on MS Paint

First jpg is series four. Second is series five.

#2 is Air Supply valve outlet

#3 is brake booster feed

#4 is vacuum to the water thermovalve

#5 is oil injector spider feed.

#6 is fuel injector air bleed feed.

Cap above #6 is not used and is capped off.


Second jpg is series four with but three nipples.

 

what is the sensor right next to the number 3? Does it need a gasket?

 

hailers is those nipples the same for a jpec motor

do you have pics

 

The gold solenoid to the right is the Air Supply solenoid and is triggered when pwr steering is used to keep the idle up.

I think the nipples have the same usage on a JSPEC.
