Having a slight drivability issue. Feels like a possible vacuum leak. Checking vacuum lines and other stuff with the dog house off. Checked the HVAC for leaks but all that stuff seems tight. The only gross things I’ve found were a kinked vapor house from a Y above the trans, down to a hardline to the tank.
And then I noticed vacuum lines along the right side frame with white tubes. Two had the nice OEM plastic line connectors, but one was basic, rubber and badly deteriorated so I replaced it. I assume it goes to the black, plastic “box” attached to the frame, kinda under the side cargo door. Am I correct in assuming that this is an EGR vacuum reservoir, hence the white lines? Hoping that’s what it is and my performance will be improved. Can’t test drive the van as it’s blocked in for the day.
When I bought my ford van this box was completely missing

did you ever figure this out and which vacuum lines goes where?
