WUMZIJ 6V Electric Fuel Pump Kit for Carbureted Engines — 5–8 PSI, 5/16" Inlet/Outlet

The WUMZIJ 6V Electric Fuel Pump Kit is an inline replacement pump engineered to deliver 5–8 PSI fuel pressure for carbureted E8011 and SP1124 applications.

This compact, metal-bodied pump is built specifically for 6‑volt electrical systems found in classic cars, specialty vehicles, and marine equipment. It swaps into carbureted fuel lines with 5/16" inlet and outlet fittings and offers clear wiring guidance for either negative- or positive-ground systems. The pump is corrosion-resistant, straightforward to install, and sized to restore steady fuel delivery for older mechanical fuel systems without extensive modification.

Will this pump work on my 6‑volt carbureted engine?

Yes — the WUMZIJ pump is designed for carbureted models that accept E8011 and SP1124 style replacements and require 5–8 PSI of fuel pressure. Its 5/16" inlet and outlet match common carburetor fuel line diameters, making physical fitment likely for many vintage setups.

• Compatible with carbureted systems specifying E8011 or SP1124 replacements.
• Delivers 5–8 PSI, suitable for most classic carburetors.
• 5/16" inlet and outlet for common fuel hose connections.

How do I wire the pump for negative or positive ground vehicles?

Wiring differs by chassis ground type: for negative-ground systems, connect the vehicle "HOT" + source to the pump's red + wire and the pump's black wire to chassis ground. For positive-ground systems, reverse those connections — vehicle "HOT" + to the pump's black wire, and the pump's red wire to ground. Follow safe battery-disconnect practices while wiring.

• Negative ground: vehicle + to pump red; pump black to ground.
• Positive ground: vehicle + to pump black; pump red to ground.
• Always disconnect battery before electrical work and secure connections.

How difficult is installation and what tools do I need?

>The inline design keeps installation simple — the pump installs directly into the fuel line between the tank and carburetor. Typical installation requires basic tools: hose clamps, screwdrivers, pliers, and possibly a short section of 5/16" fuel hose for clean connections. No specialized machining or complex mechanical adjustments are usually necessary.

• Inline swap — cut old hose and insert pump using clamps or fittings.
• Basic tools: hose clamps, pliers, screwdrivers, and replacement fuel hose.
• Follow wiring instructions for your ground type and test for leaks.

What materials and reliability features does the pump offer?

>The pump housing is made from high‑strength metal with corrosion-resistant properties to withstand fuel exposure and outdoor environments. Its design focuses on durability for long service life while keeping flow and pressure within the 5–8 PSI range expected by carburetors. Routine inspection of hose connections and electrical terminals will help maintain performance over time.

• Durable metal construction resists corrosion and wear.
• Consistent 5–8 PSI output for stable carburetor operation.
• Compact form factor for tight engine bays and marine compartments.

Who is this for: The WUMZIJ 6V Electric Fuel Pump Kit is intended for owners and restorers of vintage cars, tractors, boats, and other 6‑volt vehicles using carbureted engines that need a reliable inline replacement. It’s especially useful for hobbyists and mechanics who want an easy-to-install, metal-bodied pump that matches E8011 and SP1124 specifications and offers straightforward wiring for either negative or positive ground systems.

FAQ

Q: Is this pump compatible with 12V systems?

A: No. This WUMZIJ pump is built for 6V electrical systems and may not operate correctly or safely on 12V.

Q: What fuel pressure does the pump provide?

A: It supplies approximately 5–8 PSI, suitable for most carbureted engines requiring that pressure range.
