High quality diesel aux. tank
This tank will not fit in a 2009 or 2017 short bed ram truck. I had to do some hefty wheel well modifications which is what I was trying to avoid. It was my fault for ordering before getting the proper measurements from the tank manufacturing company. The quality of this tank is excellent. After modifications and installing the gravity feed diesel transfer kit I filled it up and it worked great. Very high quality build with some great welds.

Nice tank
Well built,easy installation. As others have stated it only holds 40 gallons. Not a problem for me but if you need the higher capacity you may want to go a size up

Good tank but filler location could be better
The tank itself is not bad and works well, but I expected the diesel fill location (the filler neck) to be positioned differently. It’s a bit inconvenient the way it’s placed. Overall, still a decent tank, just not exactly what I imagined.

Got it fast.
Looks good matches my weather guard toolbox fits under it.

No more stopping for diesel
Love the tank! I also got the install kit for my 2011 F-250, both work great! Side note--If the truck is going to sit for more than a day, close the shut off valve.

Not top quality
I bought this for my 2019 F250. When it arrived it came with lots of stickers on it because it did not come crated. The bottom of the tank was not flat at all the mounting angle that was welded on sticks off the bed at least an inch. Could have been better.

Nice tank, but...
This tank is variously described as 40 gallon, 45 gallon, and 48 gallon. According to the tag, it has a 40 gallon capacity, although dimensionally, it holds 45 gallons. It is a nice tank, but the fuel cap leaks. The cap it came with is a SpinSecure locking, vented cap. Why it has a vented cap, I don't know, since the tank is already vented. I am trying to resolve the cap issue with RDS. Update: Although RDS was unresponsive, SpinSecure sent me a new cap for no charge, and the new one does not leak.
