Hey guys. I'm trying to put all my auxillary parts back onto my rebuilt engine here, and I ran into a few problems.

My biggest problem is these vacuum lines. I don't know which goes where. I figure #4 connects to that hose with the arrow on it (Comes down from the secondary rail). I would think the rest went to the ACV, but Im runnin down to K2RD tomorrow to pic up a block off plate for that, so will I still need them?

Heres the pic:


This isn't really a problem, but what is this thing? And does it need to be screwed in until know more threads are showing on it? Cause mine is like 1/4 of the threads left and its having trouble going in...



Thanks for the help!

 

oil pressure sender

 

Pull the two vac lines off the orange(fpr) solenoid and blow into them one at a time. If air exits number four, them that number four goes to the fpr on the back of the secondary fuel rail.

 

Ok,
and what about the other 4 lines?

 

Put thread seal (the plumbers stuff) on the oil psi sending unit then snug it up in the rear housing just so long as it doesn't leak it should be fine.

 

Ya, don't tighten the sending unit till it bottoms out .. just till its snug.

 

You didn't ask about the other four.

I assume you figured the ORANGE SOLNOID out already.

Go to the BLUE solenoid(RELIEF SOLENOID). Take both its vac lines off and blow. You will find both go to that gang of four. They would normally go to the acv. I think you said you were ditching the acv.

Go to the GREY SOLENOID. Take both it vac hose off. Blow into each. Only one will go to the gang of four. It goes to the acv also. Normally the pipe on the acv that sticks straight up at the sky.

Darn if I know where the forth goes. If you had 87/88, I'd say the EGR valve, but you have no EGR. Someone else will have to figure that one out. Probably somewhere on the turbo.
