New addition to the truck. I couldn't for the life of me find a stock breather kit so I had to make one:
Had to piece together parts (in order). Breather, braided hose, fitting, rollover valve, two fittings to fit a rubber line which runs to the tank.
Decided to put it in that back channel in the bed. In order to get to it we decided to cut a hole and slide the new breather in. It was a tight fit. Fit nicely, you can barely make out the breather.
