Fuel Tank Pump Types Comparison
Various pump designs serve different fuel delivery needs across automotive, industrial, and aerospace applications.
Common Fuel Pump Types
-
Electric Submersible Pump (ESP)
Most common in modern gasoline vehicles - submerged directly in fuel tankPrevents vaporization and maintains consistent pressureIntegrated with fuel level sensor and filterExample Application
Toyota Corolla in-tank pumpOperating Pressure
40-60 PSI (typical) -
Mechanical Fuel Pump
Engine-mounted design for older vehicles and some diesel applicationsDiaphragm/plunger actuated by camshaftProne to vapor lock in hot conditionsExample Application
Carbureted Ford trucks -
High-Pressure Diesel Injection Pump
Specialized for diesel engines (up to 30,000 PSI operation)Common Rail Pump Unit Injector Pump Rotary Distributor PumpExample Application
Cummins-powered trucksPressure Range
5,000-30,000 PSI -
Hand-Operated Diaphragm Pump
Manual operation for portable applications without electricityCreates suction via flexible diaphragmIdeal for small equipment and marine useExample Application
Portable marine fuel tanks -
Centrifugal Pump
High-volume transfer for industrial fuel storage systemsRotating impeller generates flowEfficient for long-distance fuel movementExample Application
Commercial fuel stations -
Vane Pump
Precision fuel delivery for aviation and high-performance applicationsSliding vanes create consistent chambersDelivers smooth, high-pressure flowExample Application
Cessna aircraft fuel systemsKey Feature
Extreme pressure consistency
Selecting the appropriate fuel pump type depends on application requirements - from everyday automotive use to specialized industrial and aviation needs. Modern vehicles typically use submersible electric pumps, while diesel, portable, and high-performance applications demand specialized pump technologies.
