Re: 1995 Ford Windstar Question
Don't know your vehicle, but can offer some simple logic: HIGH is the high
pressure side of the sensor. EGR flow is from the exhaust to the intake
manifold (or throttle body). So the tube closer to the exhaust goes to the
HIGH port of the DPFE.
If I remember correctly, the DPFE nipples are not the same size. Unless you
replaced the tubes of cut off their ends, one should be flared or stretched
larger than the other. By the way, if you ended up replacing one of those,
hopefully you did not use a simple rubber tube; because of the high
temperature, these need to be heat resistant (possibly silicone).
