How to Select the Correct Configuration

  • Confirm the carburetor requires 4–7 PSI and that 35 GPH meets demand.
  • Confirm 12 V/24 V version, polarity, fitting size and mounting orientation.
  • Use gasoline-rated hose, filter and clamps away from heat sources.
  • Check whether a safety cut-off or oil-pressure/inertia switch is required.

Low-Pressure Fuel-System Matching

This pump is selected by its low-pressure function, tested pressure and flow range, fuel type and installation requirements.

  • Confirm the receiving carburetor or engine low-pressure circuit accepts the stated pressure range.
  • Verify tested flow, voltage, duty cycle, lift or priming limit and fitting size.
  • Use fuel-compatible hose, filtration and the required safety shutoff arrangement.
  • For diesel applications, confirm water-separator, temperature and biodiesel requirements where applicable.

Customization and Supply Options

Available configurations are confirmed against the approved drawing, performance target, fuel specification and order requirements.

Frequently Asked Questions

1.Can it feed an EFI fuel rail?

No. This low-pressure pump is intended for carbureted supply or approved transfer duty, not high-pressure EFI.

2.Will every carburetor accept 7 PSI?

No. Verify the carburetor inlet-pressure limit and add a regulator when required.

3.Is it self-priming?

Use only the priming and mounting limits stated on the approved product datasheet.

4.What information is needed for an accurate quotation?

Send the target fuel, operating voltage, required flow at maximum pressure, installation dimensions, inlet/outlet, connector, duty cycle and estimated annual volume.

5.Can the product be customized for private-label supply?

Yes, within the approved platform. Available options may include voltage, barb/thread size, connector, mounting bracket, packaging. Final scope, validation, MOQ and tooling are confirmed in the quotation.
