Hello,
In the engine compartment, there are two small in-line vacuum diaphragm or check valves that go to the fuel tank evaporation cannister and to the EGR control module or what ever it's called. These two valves are half black and half light gray and have the letters VAC molded on them. I need to know which direction each of these two valves point. for each valve, what direction does the gray end point, towards the front of the car or towards the firewall? I think I may have mine installed incorrectly. Please email me directly at jwest@oppd.com with any help that you can give me.
Thanks,
James West
