Hi guys,
On the small 2 nipple cannister bolted on the back of the OEM fd LIM ... I can't determine where the other end of the vaccuum line goes.
I was able to locate the fuel hose location on the back of the
the UIM, I'm stuck with location of the vaccuum hose to that same canister ? Various rat's nest pics seem to point to the fuel pressure solenoid, and the vaccuum diagram shows one hose from back of the LIM going to the lower front solenoid, but both of these are fully populated on my rat's nest.
Can anyone definitively tell me where this vaccuum line connects ? Thanks

 

picture please... i dont know of any canisters bolted to the LIM

 

Yep what you said doesn't make any sense. Post up some pics.

Sorry for the confusion guys. The thicker fuel line is flipped about 110* counter clockwise when sitting on back of LIM pointing towards throttle body.
Not sure if this example is from an FD, but pretty close.
The smaller vaccuum line is a few inches away from, and points towards the shortblock rear ground terminal that grounds 2 UIM groundstraps and emissions harness ground.
Since it involves a fuel line, I thought it might be fuel pressure or some sort of fuel cutoff device ?
Sorry I can't sort this on my own guys. Laptop with all my pics + notes crashed for good and all this should have been done before dropping block into car, . The good news is that once rat's nest is sorted the rest should be pretty straight forward. fingers crossed

 

still dont know what youre asking but your answer is here

I've checked all lines close to the back of the LIM on the OEM vaccuum diagram, and no luck. It's a great resource, but a lot of confusing aspects in places.
I would post one using a real rat's nest frame if I had a spare.
My thinking is it might go to a LIM nipple I missed.
Since it involves fuel, I very much want to get things right.
I usually labbeled all hoses and took lots of pics, but this one came off at some point between pulling the block and this reinstall.

 

that is the fuel pressure regulator. so the fuel line is the return, and goes to the pipe and then the tank, the vacuum line ends up at the fuel pressure solenoid, orange

 

Yep, that's the FPR, should just go to the pressure regulator solenoid.

In the vacuum diagram linked, it's the light cyan vacuum hose going to solenoid A, Pressure Regulator. Also in the diagram the pressure regulator is pointed out.

Thanks for confirming this for me, guys.
