Protecting the Fresh Water Tank/ Water Drain Fitting and the Gray Tank from Road Debris.

The location of the fresh water tank and the drain fitting at the front passenger side wheel well is highly vulnerable to damage from road debris the tire spews at it. The front facing wall of the gray tank is no different; it gets pitted and sandblasted from road exposure. I covered the exposed areas of the tanks with an anti-fatigue mat few years ago using plain silicone adhesive sealant and it held up and protected the tanks well for thousands of miles.

The fresh water drain although now protected by the mat, it is unsightly and needed an update and extra protection. I got the idea from a sprinter-source forum member (credit goes to Mein Sprinter). I bought an inexpensive plastic splash guard cover (pictured below) from a local auto supply chain. Pre fitted into the wheel well, I marked the area of the splash guard that needed to be bent inward to prevent it from rubbing against the wheel.  Using a heat gun, I slowly and evenly heated the marked area and while it is still warm, I slowly bent it inward by hand and then let it cooled down under running water. The splash guard retained it shape and was a perfect fit with no trimming needed. I slathered a good amount of silicone sealant along the top J-shaped edge of the splash guard for extra hold then secured it in place using 3 screws.
