300 Gallon Fuel Tank with Pump: The Complete Guide to Choosing the Right Setup for Your Farm, Jobsite, or Workshop

If you need a reliable on-site fuel storage solution, a 300 gallon fuel tank with pump is one of the most practical investments you can make. Whether you run a farm, manage a construction site, or operate a fleet of equipment, this size tank hits the sweet spot between capacity and portability. The bottom line: a 300-gallon tank with a quality pump saves you time, money, and downtime by keeping fuel where you need it—right on your property.

Why a 300 Gallon Fuel Tank with Pump Makes Sense

A 300-gallon fuel tank with a built-in pump is the "Goldilocks" solution for many operations. It holds enough fuel to keep your equipment running for days or weeks without needing a bulk delivery, yet it is compact enough to move around a job site or position in a barn or shed . These tanks are commonly used for fueling construction equipment, farm machinery, or fleet vehicles, making them versatile for both commercial and agricultural operations .

The key advantage is convenience. Instead of driving equipment to a gas station or waiting for a fuel truck, you can refuel on-site. This reduces downtime and keeps your crew productive. A 300-gallon tank can hold roughly 1,360 liters of diesel or gasoline, which is enough to fill a dozen pickup trucks or run a medium-sized tractor for several days .

Key Features to Look for in a 300 Gallon Fuel Tank with Pump

When shopping for a 300-gallon tank with pump, pay attention to these critical factors:

1. Tank Construction and Materials

Most 300-gallon tanks are built from 12-gauge steel, which provides excellent durability and long-term use in demanding environments . Some models use 10-gauge or 14-gauge steel depending on the design. The tank should be coated with a white industrial enamel finish to resist corrosion .

You have two main construction options:

  • Single-wall tanks: These are lighter and more affordable. They are suitable for most farm and construction applications where double containment is not required by local regulations .
  • Double-wall tanks: These provide an extra layer of protection against leaks and spills. They are often required for installations in environmentally sensitive areas or where local fire codes demand secondary containment .

2. Pump Type and Flow Rate

The pump is the heart of your fuel system. Most 300-gallon tank packages come with a 12V DC electric pump or a 115V AC pump. The flow rate typically ranges from 15 to 20 gallons per minute (GPM) .

  • 12V pumps (20 GPM): Ideal for remote locations where AC power is not available. They run off a vehicle battery or a dedicated 12V power source. Packages often include an 18-foot hose and an automatic shutoff nozzle .
  • 115V AC pumps (15-20 GPM): Better suited for permanent installations where electricity is accessible. They provide consistent power and are easier to use for high-volume fueling .

3. Filtration and Safety Features

A quality fuel system must protect your engines from contamination. Look for tanks that include a 30-micron filter to remove debris and contaminants from the fuel . Other essential safety features include:

  • Locking fill cap to prevent spills and unauthorized access .
  • Emergency vents to release pressure in high-temperature situations .
  • Pressure-vacuum vents for gasoline tanks to minimize evaporation loss .
  • Spill containment to catch drips during fueling .

4. Fuel Level Monitoring

Knowing how much fuel you have left is critical for planning refills. Most tanks come with a Krueger liquid level gauge or similar monitoring device that lets you check the fuel level at a glance .

Types of 300 Gallon Fuel Tanks with Pump

Several configurations are available to match different needs:

Farm Tanks (Single Wall)

Farm tanks are the most common type. They are designed for agricultural use and typically sit on skids. A 300-gallon single-wall farm tank with a 12V GPI 20 GPM pump, 18-foot hose, automatic nozzle, and 30-micron filter is a complete turnkey solution . These tanks are built to withstand tough environments while ensuring efficient fuel dispensing .

Double-Wall Skid Tanks

For added safety, double-wall skid tanks meet UL 142 standards for above-ground storage of flammable liquids . A 300-gallon double-wall tank with a 12V 20 GPM pump, 18-foot hose, and automatic shutoff nozzle provides reliable and secure fuel storage for farms, construction sites, and other remote fueling needs .

Portable Tanks with Fork Pockets

Some models are designed with integrated fork pockets, making them easy to move with a forklift or skid steer. These tanks are built with internal baffles to eliminate fuel slosh during transport . They are ideal for operations that need to move fuel storage between different job sites.

What to Expect in Terms of Price

Prices for 300-gallon fuel tanks with pumps vary widely based on construction type, brand, and included features:

  • Used or basic models: A used 300-gallon diesel tank with a hand pump can sell for around $795 . These are good options for budget-conscious buyers who do not need a high-flow pump.
  • New single-wall packages: A complete 300-gallon single-wall farm tank with a 12V GPI pump typically costs between $1,583 and $3,301 depending on the pump and accessories included .
  • Double-wall UL 142 tanks: These packages range from $2,756 to $5,844, reflecting the added safety and compliance features .
  • Premium models with heavy-duty pumps: Some newer models with 20 GPM 12V high-speed electric pumps, 10-gauge steel construction, and fork pockets can cost around $3,599 .

Installation and Maintenance Tips

To get the most life out of your 300-gallon fuel tank with pump, follow these practical guidelines:

  • Place the tank on level ground to ensure proper fuel pickup and prevent strain on the pump.
  • Keep the tank at least a quarter full to prevent condensation and reduce the risk of water contamination.
  • Replace the fuel filter regularly (typically every 6-12 months depending on usage) to protect your pump and engines from debris.
  • Inspect electrical connections for corrosion or looseness, which can cause voltage drops and damage the pump.
  • Listen for unusual noises from the pump—a whining or buzzing sound is a warning sign that should be addressed early.
  • Use high-quality fuel to avoid contaminants that can clog filters and damage the pump.

Choosing the Right Fuel Pump for Your Tank

While the tank itself is important, the pump is what makes the system work. If you are building a custom setup or replacing an existing pump, investing in a high-quality fuel pump is essential. A failed pump can leave you stranded and cost you hours of downtime.
