Less fuel stops

It has always been one of my pet peeves getting fuel in a crowded fuel station and nobody willing to give you an inch to get to the pump. Well today I think I might have solved that problem. I installed this 40 gallons RDS tank and now I have a range of about 900 miles on my rig. Now I will be able to get where I am going and fill the truck without the fiver attached. This is how the install went. I set the new tank inside the truck it fit perfectly. Drilled a couple of holes to hold it down. Before I locked it into place the cramped work began. I had to take the fill spout out and cut a section out so the new valve would fit in place. Then splice it all back together with hose clamps and hose extensions. Man talk about tight. It was like working in the bilges of my boat. With that done I needed to take the hose and drill a couple of holes in the truck bed one for the fuel line to attach to the new fill tube and one for the venting of the tank. This is where the holes were drilled and the tube that connects to the new tank. This shot shows the vent tube that travels down the back side of the fuel tank to the undercarriage of the truck And the fuel line going down to the fill spout




All in all a pretty fun project I will let you know how it all works in a couple of weeks. I am planning my first trip with the new set up just to see how it works. RDS seems to make a pretty darn good tank.

    Yeah you got your laws mixed up. Your talking gas we are talking diesel.

  • I'm green with envy! My fuel stops dropped drastically going from a gasser with a 26 gallon tank to my diesel with 39 gallons, but this upgrade would be great.
  • I have the 91 gallon RDS. It works great. Even switched it from one truck to the new to me truck. I like the new design for the filler cap. Mine is exposed, and I have to keep a locking cap on it. Good luck
