How does this replacement match the original Honda part?

The ultramindz unit is manufactured to replace OE part number 16700-HR3-A21 and ships as a pump assembly complete with a float. Although sold as a direct replacement, the pump may require minor connector checks to ensure a trouble-free install.

• Supplies the fuel delivery components included with the original assembly.
• Float arm may ship detached to prevent transit damage; snaps into place during installation.
• Designed to meet form, fit and basic function of the OE part number listed.

What should I check before buying or installing?

Measure connectors and note your vehicle’s emissions market (California vs. federal) before ordering. If your wiring harness or connectors are longer or different, a quick bellow connector or local mechanic can adapt the fit without affecting pump operation.

• Confirm part number 16700-HR3-A21 compatibility with your VIN or service manual.
• Measure connector length and compare to the pump to avoid mismatch.
• Check whether your ATV is a California-spec model for certain excluded years.

What should I expect during installation and service life?

Installation requires disassembly of the fuel tank and handling of fuel system components—tasks best performed by a qualified mechanic. The package includes pump and float; the float arm may arrive detached and snaps into the sender housing. Proper installation and fuel system testing ensure reliable operation.

• Package contents: 1 fuel pump assembly and 1 float (float arm may be detached).
• Professional installation recommended to prevent damage and ensure safety.
• If connectors differ in length, use an adapter or consult a mechanic to avoid strain on fittings.

Who is this for: This ultramindz fuel pump is intended for owners, repair shops and restoration specialists working on Honda Rancher, Foreman and Rubicon ATVs who need a cost-effective replacement for part 16700-HR3-A21. It's a good option when you require a pump that mirrors the original assembly’s layout and components, but remember to verify fitment for California-specific models and consult a professional for installation to ensure safe, correct operation.
