Where does this vacuum line go?

[jedwards83]

My long term fuel trim is pegged at 16, so I'm replacing suspect vacuum hoses. While in the process, this one popped off and I can't figure out where it goes. It must have something to do with the MAP sensor, because it killed my boost gauge.

Can someone please point me in the right direction?

The two ends that got disconnected are shown in your photo, next to the alternator. Route them under the alternator brace and then push the two lines back together.

Are both ends of the upper piece disconnected? Can't tell from the pic...

The two pieces go back together to form one line, I've got that. But the other end on the far right, I can't find a home for it.

if that line goes to the LIM under the SC snout, the right side should connect to the bottom side of the MAP sensor.

bottom side of the MAP sensor.

Thanks, couldn't get a good look under there until I removed it. All is well now [besides the fuel trim which is still high ].

I would suggest getting rid of that splice. If the line cracked, I am sure there are other faulty areas. This is known to crack and split at the rubber boots that slip onto the LIM, FPR and BCA.

It is still a dealer available part and I bought one this year and it ran $30 for the complete vacuum hose.

That's the last line I haven't replaced, I plan on using rubber vacuum hose instead of the dealer part. Since I no longer have the engine cover on, I have lots of options in which to route vacuum lines. I did notice the rubber boot is split at the FPR. I put some RTV on hoping for a temporary fix until I can pick up some vacuum hose that's small enough.

Most of the hoses were so brittle the broke up in pieces just trying to get them off.

You will find it is more headache and problems than just getting the complete part. Not all the fittings are the same and you will need to get differnt adapters to make it fit.

I just went through this when I was stuck in Wyoming and the local dealer did not stock it, but the one in Ohio (my destination) did.

I second that- by geting a whole kit will save yourself many many headaches.

What you are looking for is the "Vacuum Harness". There are 2 of them, the one from the TB to the Evap and the one that goes to the FPR, under the LIM and to the MAP. The one from the large port of the TB to the Evap is $17 at a dealer and the FPR - MAP one is $26, at least the last time I checked them.
