Below, we break down everything you need to know to choose the right Fill-Rite pump for your specific needs.

Why Choose Fill-Rite Fuel Transfer Pumps

Fill-Rite, now part of The Gorman-Rupp Company, has been manufacturing fuel transfer equipment in Fort Wayne, Indiana for over 60 years. The brand is known for its signature red pumps that are found on more farms, construction sites, mines, and fleet service facilities than any other brand.

Key advantages of Fill-Rite pumps include:

  1. Durable cast-iron construction – Most heavy-duty models feature cast-iron pump housings, rotors, and vanes made from iron and bronze, ensuring robust performance over the life of the product.
  2. Rotary vane technology – This proven design delivers reliable performance and can process upwards of 100,000 gallons of fuel with proper maintenance.
  3. Broad fluid compatibility – Fill-Rite pumps handle gasoline, diesel, kerosene, biodiesel blends up to B20, ethanol blends up to E15, and mineral spirits.
  4. Safety certifications – UL/cUL, ATEX, and CE listings assure the highest level of safety engineering.
  5. Limited Lifetime Warranty – Select models carry a limited lifetime warranty, with wearable components covered for 2 years and bundled accessories for 1 year.

How to Select the Right Fill-Rite Pump

Choosing the right fuel transfer pump requires evaluating your specific application, power source, and fluid requirements. Here is a step-by-step guide.

1. Determine Your Flow Rate (GPM)

The flow rate, measured in gallons per minute (GPM), should match the size of the tanks you need to fill.

  • 8 GPM – Ideal for small equipment like lawnmowers, ATVs, and recreational vehicles. The Fill-Rite FR8 Series is compact and lightweight, designed for equipment with smaller fuel tanks.
  • 15 GPM – Perfect for tractors, pickup trucks, and equipment with 15-60 gallon tanks. The 1200 Series (12V DC) and 600 Series (115V AC) are popular choices.
  • 20 GPM – Suitable for larger trucks, heavy equipment, and fleet operations. The 4200 Series (12V DC) and 700 Series (115V AC) deliver this flow rate.
  • 25 GPM – The NX Series offers 25 GPM in both DC and AC configurations, suitable for high-volume commercial use.
  • 35 GPM – The FR300 Series is Fill-Rite's highest flow AC pump, designed for heavy-duty commercial applications.

2. Choose Between DC and AC Power

Your power source determines whether you need a DC or AC pump.

  • 12V or 24V DC pumps – Designed for mobile applications on trucks, trailers, and service vehicles. These pumps connect directly to a battery and are ideal for remote job sites.
  • 115V or 230V AC pumps – Best for stationary fueling stations in garages, workshops, or depots where you have access to a standard electrical outlet.

3. Consider Your Fluid Type

Fill-Rite pumps are compatible with a wide range of fluids, but not all pumps handle all fluids.

  • Standard fuel pumps – Handle gasoline, diesel, kerosene, biodiesel up to B20, and E15 ethanol blends.
  • Chemical transfer pumps – The Sotera brand, also under Fill-Rite, offers pumps designed for acids, solvents, and lubricants.
  • DEF dispensers – Fill-Rite offers dedicated DEF (Diesel Exhaust Fluid) transfer pumps for SCR systems.

4. Evaluate Your Mounting and Installation Options

Fill-Rite pumps are designed for easy installation on standard 2-inch bung openings.

  • Bung mount – Most pumps screw directly into a 2-inch NPT threaded bung opening on the transfer tank. No bracket required.
  • Rotatable junction box – The junction box rotates 180 degrees for easier wiring and flexible installations in tight spaces.
  • Complete kits – Many models come with a hose, nozzle, suction pipe, and battery cables, so you have everything you need to get started.

Essential Accessories for Your Fill-Rite System

To complete your fuel transfer system, consider these accessories:

  1. Flow meters – Fill-Rite offers both mechanical and digital meters for accurate fuel tracking. The 800 Series mechanical meters are ideal for low-volume applications, while oval gear meters provide precise measurement for commercial use.
  2. Automatic nozzles – Auto shut-off nozzles prevent overfilling and are compatible with Fill-Rite's internal bypass valve.
  3. Hoses – Fill-Rite offers 3/4-inch and 1-inch discharge hoses in various lengths, including new 25-foot hoses for extra reach.
  4. Suction pipes – Included with most pump kits, these telescoping pipes fit tanks from 20 to 34 inches deep.
  5. TankDefender accessory – This heavy-duty support reduces stress on bung welds, extending the life of aluminum tanks.

Maintenance Tips for Long Life

With proper maintenance, a Fill-Rite pump can last for years.

  • Replace carbon vanes – These naturally wear down over time. A well-designed pump allows a technician to swap vanes and clean the internal bypass valve in under 15 minutes.
  • Clean the strainer – The built-in mesh strainer filters out particulates. Clean it periodically to prevent clogging.
  • Check seals and gaskets – Replace worn seals to prevent leaks and maintain performance.
  • Use genuine Fill-Rite parts – Over 150 different rebuild and replacement part kits are available to keep your equipment running at peak performance.
