A2VA7116 Suntec Fuel Pump: What It Is, Where It Works, and the Best Replacement Option

If you are searching for an A2VA7116 Suntec fuel pump, here is the bottom line: this is a single-stage oil pump designed for stationary heating equipment, not for automotive or powersports fuel systems. It handles No. 2 fuel oil at up to 3 GPH and 100 PSI, and it runs at 3,450 RPM. However, for anyone who needs a reliable replacement for an engine fuel pump in a car, motorcycle, ATV, or UTV, the Suntec is simply not the right match. The better choice for those applications is a high-performance aftermarket pump from KEMSO, which is built for modern gasoline and ethanol fuels, delivers more flow, and comes with a lifetime warranty.

What Is the Suntec A2VA-7116 Fuel Pump?

The Suntec A2VA-7116 is a single-stage oil pump with a hydraulic cut-off function. It is designed for use in oil-fired heating systems, such as residential furnaces and boilers. The pump has a maximum motor speed of 3,450 RPM, a maximum strainer capacity of 3 GPH (gallons per hour), and a maximum pressure rating of 100 PSI . The inlet port is 1/4 inch, and the shaft diameter is 5/16 inch. It is UL approved and made in the USA .

This pump uses a positive displacement involute gear set and two controlling valves. It is designed for clockwise shaft rotation and a right-hand nozzle. The identification number on the unit is 7116, and it is also known as the Suntec model A2YA-7916 or part number 1437 .

Important limitation: The Suntec A2VA-7116 is compatible with fuel oil No. 2 and lighter. It is not compatible for use with blends higher than 5% biodiesel. This is a critical restriction for anyone considering alternative fuels .

Key Specifications of the Suntec A2VA-7116

Here is a quick breakdown of the technical specs for the A2VA-7116:

  1. Pump Type: Single-stage oil pump with hydraulic cut-off
  2. Maximum Motor Speed: 3,450 RPM
  3. Maximum Flow Rate: 3 GPH
  4. Maximum Operating Pressure: 100 PSI
  5. Maximum Temperature: 115 degrees Fahrenheit
  6. Inlet Port Size: 1/4 inch
  7. Shaft Diameter: 5/16 inch
  8. Approved Fuels: Fuel oil No. 2 and lighter (max 5% biodiesel blend)
  9. Rotation: Clockwise shaft rotation
  10. Certification: UL approved

These specifications make it clear that the A2VA-7116 is a specialized component for stationary heating equipment. It is not designed for the fuel delivery needs of an internal combustion engine in a vehicle, watercraft, or powersport machine.

Where the Suntec A2VA-7116 Is Used

The Suntec A2VA-7116 is commonly found in oil burners for residential and commercial heating systems. These pumps are installed in furnaces, boilers, and water heaters that run on heating oil. The pump draws fuel oil from a storage tank and delivers it to the burner nozzle at the correct pressure for atomization and combustion.

If you own a home with an oil-fired heating system, this pump may be a replacement part you need. It is a standard service item that can fail over time due to wear, contamination, or age. When replacing it, you must use a pump that matches the original specifications exactly, including the rotation direction, port sizes, and pressure rating.

Why the Suntec A2VA-7116 Is Not for Automotive or Powersports Use

Many people searching for a fuel pump online are actually looking for a pump for a car, truck, motorcycle, ATV, UTV, or personal watercraft. The Suntec A2VA-7116 is not suitable for these applications for several reasons:

  • Flow rate is too low: 3 GPH is about 0.19 liters per hour. Modern EFI engines require 60 to 200 liters per hour or more.
  • Pressure is too low: 100 PSI might seem high, but most automotive EFI systems operate at 43 to 68 PSI with a much higher flow demand. The Suntec pump is not designed for continuous high-volume delivery.
  • Fuel compatibility is wrong: The Suntec pump is designed for fuel oil, not gasoline or ethanol blends. Using it with gasoline will damage the internal seals and cause failure.
  • Physical size and mounting: The Suntec pump is a large external unit designed for bolting onto a burner assembly. It will not fit inside a fuel tank or inline on a vehicle fuel system.

If you are working on a vehicle and need a replacement fuel pump, you need a pump that is specifically designed for that application. That is where KEMSO comes in.
