The Swap project is coming along fairly well. I've decided to try to start the engine before I install it into the truck.
So I looking around on the web and forums trying to find out whats what on the injection pump and where the hoses connect up to. So I have pics of the Items in question.
First is the pic below.
The thing with the little dot of pink paint on it.
Is this an HAC ( high altitude compensator ) or possibly the boost compensator ??
And what does its little hose plug into ?
Here is the next one.
Maybe this is the boost compensator ??
What does its little hose attach to ??
..
And the last one...is this gadget with the two hoses coming out of it that go up to the water system a fuel heater ??
Yes, I believe the first one is a boost/ altitude compensator. I still haven't figured out where the vacuum line goes though. The other one is a cold start advance of some sort.
Rustbucket,
Thats my guess too. A boost compensator.. I've been searching the internet for a picture that will reveal some clue on the placement of the vacuum line.
are you thinking the middle pic is the cold start ? Or the bottom one..
Thanks Rustbucket....
I found a video on youtube where the guy pans around the engine. I'm fairly certain the boost comp plugs into the intake manifold.
As for the gadget right under it.. not sure yet.. possibly the intake manifold ???

. The boost comp I believe gets high pressure off the intake manifold (somewhere post turbo) because, the manual I'm reading states the test procedure is to pump it up to 19 PSI for 10 minutes.
As for the other gadget, it looks like the A/C idle up actuator.
I found this PDF manual on IH8TE Mud. I'll try to find the link. Hope it helps!
