03 navigator vacuum line (i think) turning to sand if touched need to no the part #
I have a 03 navigator and I got a p0174 code. I found the vacuum line that everyone was taking about that goes bad. I believe the part number for that is: YS4Z-6A614-BA, but that is a ford part and not a lincoln part; is that ok to use?
Also, while inspecting the other lines, i found a line that was disintegrating; when you touch the line, it starts turning into sand (You can see the black dust on the left side of the pic). It is the line that connects to the green thing on the right of the pic. Anyone know what this line is called and what part number it is so i can replace it?
