On the intake system after the throttle plates and before the engine's inlet ports. Has to measure manifold pressure.

This might be for the oil injection line. I'll look at mine in the morning. It's in the polebarn and I'm settled in the warm house for the night. Cold, snowing with some wind tonight.

I just worked on one of those, I saw that and looked for quite a while where the line was supposed to go and never found it, the sled runs great with a new fuel pump relay so i figured where that line went just needed atmospheric pressure because my service book doesnt show a line hooked up there either

I believe it's meant to be vented to atmosphere, should have a tube on it dropped down, just to keep snow/water out of it. I ran a 580 EFI for about 5 years.

Snowest's forum has a good group of people who are knowledgable on those sleds.
