Hi, I've just acquired a 1997 DT150 efi that has been "worked" on by the previous owner. I removed the oil tank today to clean it and found that the little brass nipples on the intake that were used to inject oil on the older efi's didn't have any plugs or hoses on them. I can't find any mention of what to do with them in my manual.
Keep in mind that this engine only injects oil into the VST. These are the fittings that are right behind the injectors.
Any help is appreciated.

I just realized that the pressure sensor isn't connected to anything. Are these related? Where does the pressure sensor connect to?

What pressure sensor are you speaking about?

Sounds like some one has been mixing up parts from different motors maybe if you have parts without stuff to hook them up to

No, that sensor is meant to be there. I need to get a hold of a factory service manual.

Okay, according to the factory service manual the nipples are air jets and left open and the pressure sensor only measures atmospheric pressure not manifold. Problem solved.
