Built for Real Farm Work
This kit is designed for FillRite 300 series fuel transfer pumps, the workhorses you’ll find in fuel tanks, service trucks, and farm shops across the country. Whether you’re pumping diesel for your tractors, gasoline for equipment, or heating oil for the shop, these pumps handle the daily grind of keeping fuel where it needs to be.
Made to Last
FillRite builds these components to handle the wear and chemical exposure that comes with constant fuel handling. The rotor and vanes are manufactured to exact tolerances, ensuring proper clearances for maximum pumping efficiency. The shaft seals use fuel-resistant materials that won’t break down from exposure to modern fuel blends.
Good to Know
Plan on about an hour for the rebuild if you’re handy with tools. Keep everything clean during disassembly—even small particles can damage the tight clearances in the pump motor. Mark the pump housing orientation before taking it apart to ensure proper reassembly. Prime the pump with a little fuel before initial startup to avoid dry running the new components.
