In the photo below we see the sand line bracket installed on the truck sideframe. According to the directions on the parts package, you can slip a length of wire insulation over the "nub" to simulate the hose. As mentioned before there are several methods of installing this line. The method we'll use here differs slightly from the directions on the parts package.

What we are going to do is actually remove the protrusion off the end of the bracket as shown in the first photo. A pair of sprue nippers or a sharp hobby knife will make quick work of this.

In this next photo we see that the little "nub" has been removed.
