The front brake lines on the 1038 had already been scavenged prior to our restoration of it. After ordering the proper brake line 4710-01-186-1016  also known as 5584142 (Fig 159, Item 10), and going to install it, it was somewhat confusing based on the parts manual.
From the parts manual, it appears Item 10 goes in front of the crossmember. However, after researching brake lines on the 998, we learned the tubing starts on the rear side of the crossmember and loops through to the front side as indicated in the following picture.
Below is the front RH brake line mounted in the M1038.
Note the use of the 3/8-16 self threading screw (or bolt) 5305-01-236-4349  discussed in another article.
The lesson is exploded views in the parts manual are not always accurate. A big example of these inaccuracies is the rear vent lines (Fig. 149), which appear to have been flipped left to right. We will address these discrepancies in another article.
