I have read several posts from guys looking at the nipple and wondering how water can get it. Just remember guys water can get in like crazy when the truck is moving. Wheel spray, 70 MPH winds, passing vehicles, slush, driving rain. If you think water is just going to roll off and follow gravity, think again. Put a hose on it, and secure it pointing down! We are talking about a whole $4.00 in parts versus several grand damage or flush.

My .02 worth

 

The same engineers put that tank on there that droped the 4th gear lockout from the 2005 models. What are these people thinking ???

 

Yup, shades of Schysler Corporation, circa 1975!
