The DeeZee Way

Dodge Ram Pickup

I pull a 42-foot fifth wheel with a ram 3500 diesel. I purchased this tank to extend my range before I need to fuel up again. With this extra 40 gallon capacity I can usually get to a campsite and then unhook and find cheaper diesel away from the interstate. I installed a inline fuel pump with a switch on the dash so when I get down to a quarter of a tank I flip the switch and keep on rolling. A great product from etrailer, well-built and serves my purpose.



by:

So far so good, ready to mount it in the back of the pickup and put lines right to the fuel tank fill hose



by:

pretty easy install, all parts were packaged, spacers for the tangs should have been about 3/16 taller, I made a shim pretty easily, so no problem. Very happy with the purchase.

Great for what it is

Looks good and works great

  • Thread and Fuel Line Size Dimension for the DeeZee Connector Kit # DZ97960
    The fuel line that comes with the Connector Kit # DZ97960 that you referenced is 5/16 inch and the fitting that you referenced that threads into a fuel tank like the part # DZ91752X is 5/8 of an inch. I confirmed this with my contact at DeeZee.

  • Does Connector Kit For DeeZee Truck Bed Auxiliary Tank Have Automatic Shutoff
    The Connector Kit, part # DZ97960 is designed to work with an auxiliary tank like part # DZ91752X. This system has a gravity feed to transfer diesel fuel from your auxiliary tank to your OEM tank but there is no automatic shutoff. I called my contact at DeeZee and they told me that some trucks have a sensor and if the valve is left open all the time and allowed to empty fuel into the primary tank, you may get a code or check engine light. As you can see in the attached photo, there...

  • Are Mounting Tabs of DeeZee Truck Bed Auxiliary Tank # DZ91752X Included in Dimensions
    The mounting tabs of the DeeZee Truck Bed Auxiliary Tank # DZ91752X are not factored into the overall dimensions of the 59-1/2" long x 9" wide x 19" tall. They would add an additional inch to the dimensions.

  • Can Fuel Pump Be Added to DeeZee Auxiliary Fuel Line Kit DZ97960
    DeeZee Connector Kit # DZ97960 is designed to make a gravity feed connection between an auxiliary diesel tank like # DZ91752X and your vehicle's diesel tank. This kit is not intended to connect the aux tank to your engine fuel line but to your standard diesel fuel tank. There is no reason you could not add a suitable diesel fuel pump to the setup to speed up the flow from tank to tank, but since the auxiliary tank is usually much higher up than the vehicle tank the gravity flow usually...

  • Companion Slider 5th Wheel Hitch and Air Bag Helper Springs for a 2017 Ram 2500 Crew Cab 6.7L 4x4
    I will be happy to help you out. First, to use the B&W Companion Slider # BWRVK3400-5W you will need the proper installation kit. For the Companion hitches the installation kit also happens to double as a gooseneck hitch. For your 2017 Ram 2500 short bed use # BWGNRK1384-5W. For air bags I recommend the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88289. These springs are not only air springs; they have a jounce bumper inside for additional support. I also recommend a compressor...

  • Tool Box and Auxiliary Tank for 2018 Ram 3500 Long Bed
    If you want a single item that can both store tools and supply additional fuel capacity for your Ram 3500 long bed you might consider the DeeZee Combo Auxiliary Tank # DZ92740X. This unit combines a 43-gallon tank and a tool chest in one product that measures 54 long x 18 deep x 17-3/4-inches tall. If you prefer to have the tool box near the rear of the bed then instead you could use the 38-gallon tank # DZ91752X at the cab and then use left and right black wheel well tool boxes # DZ95B...

  • Hard Retractable Tonneau Cover Compatibility with Auxiliary Fuel Tank
    The RetraxPRO MX Hard Tonneau Cover - Retractable - Aluminum - Matte # RT80233 can absolutely install over an auxiliary fuel tank. You will just need to account for the header of the unit and the height or location of your auxiliary tank or transfer tank. For instance the DeeZee Truck Bed Auxiliary Tank - 38 Gallon # DZ91752X has a height of 19 inches and with the fuel cap 22-1/2 inches. You would need your bed rails and tonneau cover to not only exceed that height but also allow that...

  • How to Determine if DeeZee Truck Bed Auxiliary Tank # DZ91752X Will Fit Under Tonneau Cover
    The overall height including the cap for the DeeZee Truck Bed Auxiliary Tank # DZ91752X that you referenced is 22-1/2 inches. We've found that it typically fits pretty easily under tonneau covers like what you see in the attached picture, but you should measure from the bottom of your tonneau to the floor of the truck bed to be sure.

  • Can DeeZee Truck Bed Auxiliary Tank DZ91752X Be Used with Pump
    The DeeZee Truck Bed Auxiliary Tank # DZ91752X is designed to be used by itself for a gravity feed connection with the truck's tank (by way of the Connector Kit # DZ97960), and since the tank will be much higher than the truck's tank this typically provides a sufficient flow rate. With that in mind there's also no reason it couldn't be used with an existing pump to help speed up the flow. I have attached a short video demonstration on this tank below in which our installer actually calls...

  • Is Hardware Included with DeeZee Truck Bed Auxiliary Tank

  • Will DeeZee Truck Bed Auxiliary Tank # DZ91752X and Kit # DZ97960 Fit 2008 Chevrolet Silverado 2500
    The DeeZee Truck Bed Auxiliary Tank, # DZ91752X, and Connector Kit, # DZ97960, will work for your 2008 Chevrolet Silverado 2500 HD provided it is a diesel and has the 8 ft bed, a standard 6-1/2 ft bed, or the crew cab with 5-1/2 ft bed. I spoke with my contact at DeeZee and in order to fill the truck tank, you will need to be stopped with the engine turned off. You can plan on it taking 15 to 20 minutes to fill a 25 to 35 gallon tank using the gravity feed setup. The fill valve can not...

  • Transfer Tank /Tool Box Options with Soft Tonneau Cover
    The TruXedo TonneauMate Truck Bed Toolbox Crossover Style # TX1117416 is perfect for any truck owner with a tonneau cover. The toolbox fits under tonneau cover, mounts at the front, back or middle of the bed, and is elevated for full access to the truck bed floor. The dimensions are 55.38" long x 22.25" wide x 14.75" deep. I was unable to find a transfer tank tool box combo under 18 inches tall. All the combos that fit your 2015 Ford F-350 Super Duty are taller than what you want.

  • How To Add a Fuel Tank To a Truck with 5th Wheel Hitch In Bed
    Yes, the best option we can offer you to add fuel capacity is with the DeeZee Truck Bed Auxiliary Tank part # DZ91752X which should fit in the space you have between the cab and 5th wheel hitch no problem as it is only 9" deep. I don't have any specific measurements on different hitch/truck combos but the above will work for most on the market today. The DeeZee Truck Bed Auxiliary Tank will provide up to an additional 38 gallons of extra fuel. The DeeZee Combo Auxiliary Tank part # DZ92740X...

  • How Does DeeZee Truck Bed Auxiliary Tank Install to 2017 Ford F-350 Diesel
    DeeZee is the manufacturer of the Connector Kit for DeeZee Truck Bed Auxiliary Tank # DZ97960 and they test fit this on your 2017 Ford F-350 and found that it fit and worked well. While we haven't done the test fit DeeZee has and they would be more of an authority on the fit of their products since they are the ones who designed it and give the official fit list. From the research I did on your truck the filler neck should be a hard line that feeds into a rubber line where this would attach...

  • Can the DeeZee Transfer Tank # DZ91752X Use the Drain Plug to Gravity Feed Fuel for Primary Tank
    You will want to use the DeeZee Truck Bed Auxiliary Tank # DZ91752X which meets federal DOT requirements for UN31A and UN31B tanks. I confirmed this with my contact at DeeZee. This tank measures 59-1/2" long x 9" wide x 19" tall and it comes with a limited lifetime warranty. You will want to compare the dimensions with what you have in your 2005 Ford F-250/F-350 Super Duty to ensure it will fit in the location you chose. Keep in mind that the cap adds another 3-1/2" to overall height. I...

  • Will 5th Wheel Hitch Work on 2011 Ford F-250 6-3/4' Bed with In-Bed Fuel Tank
    I have a few options for you here but you won't be able to use a traditional fifth wheel hitch setup with your existing in-bed auxiliary tank, there simply isn't enough room. The base rails are going to hit on the hold down flanges so you won't even get to the point where the hitch smacks the fuel tank. If you had a long bed your chances would be increased but with a short bed it's not possible. I don't know of the dimensions of the existing tank but we do offer shallow options like the...

  • Does DeeZee Truck Bed Auxiliary Tank Come with Vented Cap
    The DeeZee Truck Bed Auxiliary Tank # DZ91752X does come with a vented cap and it will also prevent any liquids from coming out during travel as long as you don't overfill it. I reached out to my contact at DeeZee who confirmed this.

  • Auxiliary Fuel Tank for a 2013 Ram Short Bed
    We do have some auxiliary fuel tanks so to determine if any will fit your requirements you would need to go by the dimensions. Tank # DZ91752X measures is 59-1/2 inches across, 9 inches front to back, and 22-1/2 inches tall including the cap. This is the best option since all of the others are much wider and would interfere with the 5th wheel hitch for sure.

  • Is DeeZee Truck Bed Auxiliary Fuel Tank Compatible with Gasoline?
    The DeeZee Truck Bed Auxiliary Tank - Rectangle - Aluminum - 38 Gallon # DZ91752X are only intended for using Diesel fuel according to my contact at the manufacturer. It would be a large liability for them to sign off on using it for gasoline because it is much more explosive than diesel fuel. It will technically work for gasoline, but it is not recommended and would not be warrantied.

  • Recommended Hardware Size To Install DeeZee Truck Bed Auxiliary Tank
    In order to install the DeeZee Truck Bed Auxiliary Tank part # DZ91752X it is recommended to use 5/16" x 2-1/2" hex head bolts with 5/16" flat and lock washers. The Connector Kit for DeeZee Truck Bed Auxiliary Tank part # DZ97960 would then be correct for the fittings/lines.
