With over a century of engineering history, Tuthill offers a wide range of hand-operated, electric, and DC-powered pumps designed for drums, tanks, and portable applications. Whether you’re a contractor, farmer, or power sports enthusiast, selecting the right Tuthill pump depends on your flow rate needs, power source, and specific fuel compatibility. Below, we break down the key types, features, and considerations to help you make an informed purchase.

A Brief History of Tuthill Pumps

Tuthill’s story began in 1892 when James B. Tuthill, a Chicago brick merchant, invented a small internal gear pump to inject fuel oil into a boiler mounted on his trucks. This innovation led to the formation of the Tuthill Pump Company in 1927, and by 1961, the company had acquired Ossian Engineering Company, launching the Fill-Rite brand of fuel and metering products . Today, Tuthill pumps are recognized globally for their rugged construction, durability, and performance. The Fill-Rite line, often called “the red pump,” is a staple in the petroleum and fuel delivery industries .

Types of Tuthill Fuel Pumps

Tuthill offers several categories of fuel transfer pumps, each suited to different applications. Here are the main types:

1. Hand-Operated (Manual) Pumps
These are ideal for low-volume, occasional fueling without electricity. Key models include:

  • Fill-Rite FR152: A piston hand pump that delivers 20 gallons per 100 strokes, compatible with diesel, gasoline, light oil, and kerosene. It features a cast aluminum housing, 2” NPT bung mount, and comes with a telescoping suction pipe and 8-foot hose .
  • Fill-Rite FR112/FR112C: Delivers 10 gallons per 100 revolutions. The FR112C includes a counter for tracking volume .
  • Fill-Rite SD62: A rotary vane hand pump that delivers 7.5 gallons per 100 revolutions, suitable for diesel, kerosene, and machine oil .

2. Electric AC Pumps (115V/230V)
These are designed for higher-volume, continuous-duty applications. Notable models:

  • Fill-Rite FR700V: A 115 VAC, 20 GPM rotary vane pump with a 1/3 HP motor, cast iron construction, and 30-minute duty cycle. It works with diesel, gasoline, E15, kerosene, and biodiesel up to B20 .
  • Fill-Rite FR701V: Similar to the FR700V but includes a mechanical meter, delivering 18 GPM .
  • Fill-Rite FR700VG: A 230 VAC version for international or industrial applications .

3. DC-Powered (12V/24V) Pumps
These portable pumps are perfect for off-grid or mobile fueling. Key examples:

  • Fill-Rite RD8: The industry’s first portable, UL-listed explosion-proof DC-powered pump for gasoline and diesel. It delivers up to 8 GPM, weighs only 7.5 pounds, and can be foot-mounted, handheld, or bung-mounted. It features a 30-minute duty cycle and a quick-connect power cord .
  • Tuthill Mobile Re-Fueling Pump (Model 81211): Operates on 12V, delivers up to 15 GPM, and includes a flow meter. It has a UL-listed explosion-proof motor, telescoping suction pipe, and 12-foot nitrile hose .
  • Fill-Rite FR1210H: A 12-volt cast iron pump that delivers 15 GPM, with a 22- to 40-inch telescoping suction pipe and 18-foot battery cable. Suitable for diesel, gasoline, kerosene, and mineral spirits .

4. Marine Fuel Pumps
Tuthill also manufactures mechanical and electric fuel pumps specifically for marine environments. These pumps are built with corrosion-resistant materials for reliable fuel transfer in boats and other watercraft, ensuring efficient operation even in harsh conditions .

Key Features to Consider

When choosing a Tuthill fuel pump, pay attention to these critical specifications:

  • Flow Rate (GPM): Hand pumps typically deliver 7.5 to 20 gallons per 100 strokes or revolutions. Electric pumps range from 8 to 25 GPM, depending on the model .
  • Compatibility: Most Tuthill pumps handle diesel, gasoline, kerosene, and light oils. Some models are also compatible with biodiesel (up to B20) and E15 ethanol blends .
  • Mounting Options: Pumps can be bung-mounted (2” NPT), drum-mounted, tank-mounted, or used as portable handheld units .
  • Construction Materials: Cast aluminum is common for hand pumps, while cast iron is used for heavy-duty electric models. Both offer excellent durability .
  • Safety Certifications: Look for UL/cUL listing, especially for pumps handling flammable liquids. Explosion-proof motors are available for DC models .
  • Duty Cycle: Electric pumps have a duty cycle rating (e.g., 30 minutes). For continuous use, consider models with higher or continuous duty ratings .

Applications and Use Cases

Tuthill fuel pumps are versatile and can be used in many settings:

  • Agriculture and Farming: Filling tractor, combine, and irrigation engine fuel tanks from drums or bulk tanks.
  • Construction and Landscaping: Refueling heavy equipment, generators, and portable fuel caddies.
  • Power Sports and Recreation: Filling ATVs, personal watercraft, boats, and snowmobiles without lifting heavy cans .
  • Fleet and Commercial Operations: Transferring fuel to pickup truck tanks, above-ground storage tanks, and totes .
  • DIY and Home Use: Draining old fuel from stored vehicles or transferring kerosene for heating.

Maintenance Tips for Longevity

To keep your Tuthill pump running smoothly:

  • Use a clean fuel filter: Replace the built-in strainer or inline filter regularly to prevent debris from damaging internal components.
  • Avoid running the pump dry: Running a pump without fuel can cause overheating and wear, especially for electric models.
  • Store properly: When not in use, keep the pump in a dry, clean area. For hand pumps, ensure the suction pipe is clean and free of corrosion.
  • Check seals and gaskets: Over time, seals can degrade, especially with ethanol-blended fuels. Replace them as needed.
  • Follow the duty cycle: Do not exceed the recommended run time for electric pumps to prevent motor burnout.
