Real quick can any one tell me what the three vacume hoses hook up to on the back of the intake manifold facing the fire wall. I got two of them hooked back up but I can't figure out where the last one goes. Thanks in advance...

 

What year car, and model.

 

my fault I was'nt thinking when I wrote this at all. its a 88 turbo 2.

 

hmmm.

Secondary Injector air bleeds
OMP injector Bleeds

Can't remember what the third one is but It's on the LIM.

 

Sorry to sound so retarded but what does OMP stand for and LIM?

I've been looking for a while and can't find where that hose is supose to connect to.

 

OMP = oil metering pump
LIM = lower intake manifold

 

Only one is vacuum. That is the bottom one and it goes to the water thermo valve for the secondary throttle plates.

The largest is a filtered air supply for the oil injecotors.

The other is for the PRIMARY fuel injector air bleeds. It supplys a filtered air source for the primary injector air bleeds.

There is a free fsm available online.

 

I hate to ask but whats a FSM?
