I need to replace the IWE vacuum line that connects to my front, driver side wheel (2004, FX4, SCREW). If I call the dealer, they want a bunch of money, so I would like to try to save a few bucks by getting it online.

If I use my VIN & lookup the part online via (FordParts.com), I get the number: 3A788, description: locking hub vacuum tube, and the price is about $15. However, there is nothing showing where or what that part is. From the diagram, it appears that the part number I need is 3A785, which is $75.

Does anyone know what the correct part number is, or how to tell? Or is there an aftermarket part/brand that anyone would recommend? My truck has a 2" leveling kit, so getting longer lines would probably help prevent the lines from coming undone at the wheel hub.

 

You can just use generic vacuum line from any auto parts place, as long as the inside diameter is the same. You can cut the length to fit your lift application and tape or bundle tie the vacuum and vent lines together to route them in a similar fashion to stock.
