Is a Fill-Rite 12V Pump Practical for Dual 55-Gallon Barrels

The Fill-Rite Legacy and Pump Design
Fill-Rite, a division of Tuthill Corporation founded in 1927, has long been a trusted name in fuel transfer systems. Their 12-volt DC pumps are widely used in agriculture, construction, and fleet fueling, especially in remote or mobile setups. Designed for diesel, gasoline, and kerosene, these pumps typically deliver 10–15 gallons per minute and are built with cast iron housings, thermal overload protection, and self-priming rotary vane mechanisms.
The classic FR1210G model, for example, has been in production for decades and remains popular for barrel-mounted fueling. With over 100,000 units sold globally, Fill-Rite pumps are known for their reliability and ease of maintenance.
Terminology Notes

• Self-Priming: The pump can draw fluid without manual priming, provided the suction lift is within design limits.
  
• Rotary Vane: A pump mechanism using sliding vanes to move fluid, offering consistent flow and pressure.
  
• Thermal Overload Protection: A safety feature that shuts off the motor if it overheats.
  
• Suction Lift: The vertical distance between the fluid source and the pump inlet.
  

Setup for Dual Barrel Operation
Running a Fill-Rite 12V pump across two 55-gallon drums requires careful planning:

• Manifold Design: Use a Y-fitting or selector valve to draw from either barrel. Avoid simultaneous suction unless using a balanced manifold with check valves.
  
• Mounting: Secure the pump to a bracket or drum bung adapter. Ensure the suction tube reaches the bottom of each barrel.
  
• Power Source: A 12V deep-cycle battery or vehicle system is sufficient. Use fused wiring and weatherproof connectors.
  
• Flow Rate: Expect 10–15 GPM depending on hose diameter, fluid viscosity, and head pressure.
  

Operators often mount the pump to one barrel and use a transfer hose to equalize levels or switch suction manually. Some prefer quick-connect fittings for fast barrel swaps.
Operator Anecdotes and Practical Advice
One contractor in Montana used a Fill-Rite FR1210G to fuel skid steers from dual diesel barrels mounted on a trailer. He installed a selector valve and ran 12-gauge wire from the truck battery. After 3 years, the pump still ran strong, though he replaced the vanes once due to wear from winter diesel.
Another operator in Texas noted that his pump struggled when the suction hose was kinked or the barrel vent was closed. He drilled a small breather hole in each drum cap to prevent vacuum lock.
A mechanic in Alberta recommended using a spin-on filter between the pump and nozzle to catch debris and water—especially when fueling Tier 4 engines.
Preventive Measures and Recommendations

• Vent Barrels Properly: Prevent vacuum lock and improve flow.
  
• Use Fuel Filters: Protect engines from contaminants.
  
• Inspect Vanes Annually: Replace if worn or chipped.
  
• Secure Wiring: Prevent shorts and thermal overload trips.
  
• Label Selector Valves: Avoid cross-contamination between fuel types.
  

Conclusion
A Fill-Rite 12V pump is a practical and reliable solution for fueling from dual 55-gallon barrels, provided the setup is well-designed and maintained. With proper manifold routing, venting, and filtration, operators can achieve consistent flow and long service life. Whether fueling compact equipment or managing remote operations, this pump remains a trusted tool in the field. Its simplicity and durability make it a staple in mobile fueling systems across industries.
