Transfer Tanks With Pumps

What a Transfer Tank With a Pump Does

A transfer tank with a pump turns your truck into a mobile fueling station. The tank rides in the bed, the pump draws fuel out through a hose and nozzle, and you fuel equipment wherever it sits: excavators, tractors, generators, skid steers, or another vehicle. No fuel cans, no trips back to the station, no downtime waiting on a fuel truck.

This is the difference between a transfer tank and an auxiliary tank. An auxiliary tank feeds your own truck and needs no pump on the diesel side. A transfer tank dispenses to something else, and dispensing is what the pump is for.

What Goes Into a Pump Setup

A working dispensing setup is the tank plus a few pieces that do the actual fueling:

• The pump. 12 volt electric pumps run off the truck's battery. Common flow rates are around 8 to 15 gallons per minute, which fills most equipment tanks in a couple of minutes.
• The nozzle. Manual nozzles stop when you release them. Automatic shutoff nozzles stop on their own when the tank being filled is full, the same way a gas station nozzle behaves.
• A meter, if you need to track gallons dispensed per machine or per job.
• A filter, which matters more than people expect. Fuel picks up water and particulate in storage, and modern diesel injection systems are unforgiving about both.
• A hand pump as the no-power alternative. Slower, but nothing to wire and nothing to fail.

Mounting a Pump on the Tank

Our aluminum transfer tanks are built with two 2 inch NPT reinforced bungs, one on each side, so the pump can be mounted on whichever side suits how you park and work. The second bung takes the vented lockable fill cap. Tanks can also be ordered with a notch cut for pump clearance when the bed is tight.

If you plan to drive with the pump attached, note that the Severe Series tanks carry a DOT permit that allows transport with the pump in place, along with heavier .190 inch aluminum construction and a lockable SpinSecure vent cap.

Choosing the Tank Under the Pump

• Capacity. Our rectangle, L-shape, and wedge transfer tanks run from 38 to 110 gallons. Size to how much equipment you feed between refills, and check your payload. Diesel weighs roughly 7 pounds per gallon.
• Two fuels at once. Split tanks are built as two separate compartments in one body, so you can carry diesel on one side and gasoline or DEF on the other. Each side has its own fill point.
• Tools in the same footprint. A tank and toolbox combo puts lockable storage and fuel capacity in one unit, which matters when the bed is already full.
• What you can haul. These tanks are built under a U.S. DOT Special Permit and are legal for gasoline, diesel, kerosene, methanol, and aviation fuel, for private, commercial, and state use.

Adding a Pump to Your Order

We supply pump, nozzle, meter, and filter packages matched to the tank you choose, quoted per setup rather than sold off the shelf, because the right pump depends on what you are fueling and how often.

Tell us the tank you are looking at and what you need to fuel, and we will put together the setup and the price. Use the contact form or call us at (863) 261-8388. If you already know the pump you want, send the part number and we will quote it against your tank.

Common Questions

Can I dispense gasoline with a transfer tank?

Yes. Our aluminum transfer tanks are DOT approved for gasoline as well as diesel, kerosene, methanol, and aviation fuel. Dispensing gasoline requires a pump rather than gravity flow.

Can I drive with the pump attached to the tank?

The Severe Series tanks carry a DOT permit that allows transportation while the pump is attached. For other tanks, check the permit conditions for your setup before driving with a pump mounted.

Do I need a filter?

It is strongly recommended for diesel. Stored fuel collects water and particulate, and a 10 micron filter is cheap protection for the injection system on whatever you are fueling.

Can I add a pump to a tank I already have?

If the tank has a 2 inch NPT bung and is vented properly, usually yes. Send us details on the tank and we will tell you what fits.

How fast do the tanks ship?

Most tanks ship within 2 to 3 business days. Adding a gauge or powder coat adds about a week.

Start With the Tank

Browse truck bed transfer tanks from 38 to 110 gallons in rectangle, L-shape, wedge, split, and double wall bodies, or see tank and toolbox combos. Then use the contact form or call (863) 261-8388 and we will match a pump setup to it.
