I need some help with my Check Valves. I took these things apart without writing down where each goes (stupid me). I already took a look at the colored vacuum diagram but it's kind of vague.

Just to make sure is this the way they go?

Double Throttle Control Solenoid - Small Green/White Check valve
Vacuum Chamber - Large Green/Black Check Valve with filter
Pressure Tank - Large Green/Black Check Valve with filter
Back of UIM - - Small Green/White Check valve

All check valves face the direction of the UIM.

Is this correct? Also does it matter which fitting I put the check vavles into on the front of the UIM? If it does matter can someone tell me where they go?

Thanks.

That's right.

 

One more question. I just took off the UIM and it looks like the check valve was placed on the wrong tube. The vacuum diagram under my hood and the color vacuum diagram that's posted on the net don't match up.

Is the check valve in the picture supposed to be on the hard pipe all the way to the left or is it correct as is?

The colored diagram states that the check valve goes to the Switching Solenoid but i found the check valve connected to the EGR Solenoid.

 

It should go on the left tube, to the switcing solenoid.
