It's just my opinion but I think some of the guys get too wrapped up in these roll-over vents. Don't get me wrong, they're a good idea, but my truck is not a daily driver. It's a nice weather weekend driver. As such, I decided to go with just a venting system. I'm not looking to start a whole discussion on roll-over vents. This was just my decision not to use one.
If you look at the Rick's Tank in the picture, you'll see two vent locations. I was told to tie both of those together into a section of fuel hose and coil it up near the bottom of the bed, or on top of the tank. Rick's also said if I wanted to use just one of the connections I could try it to see if it works alright. I plugged the one connection and installed a barbed fitting on the other. I ran my vent line up inside the passenger side bed wheel well where it is concealed and protected. It is higher then the fill connection, which is what I wanted.
