Threlaco 2 Pcs Electric Fuel Pump Kit 12v Universal Low

The Threlaco 2-piece 12V electric fuel pump kit supplies two low-pressure inline pumps (4–7 PSI) plus filters and clamps for reliable fuel transfer in engines with carburetors.

Whether you’re repairing a small engine, replacing a worn pump, or adding a backup to a boat or lawn machine, this kit bundles two universal 12V inline pumps with matching fuel filters and hose clamps so you can install and run quickly. Each pump (model HEP-02A) is rated for low-pressure fuel delivery, fits standard 5/16" fuel lines, and is built with copper-clad aluminum components for corrosion resistance and lightweight durability.

How does this pump fit my mower, generator, or boat?

The Threlaco pump is designed as a universal inline solution for many 12V carbureted engines. It uses 5/16" hose connections and a simple two-wire installation so it integrates easily with existing fuel lines and mounting points.

• Compatible with 12V systems in cars, trucks, boats, lawn mowers, generators, and small engines.
• 5/16" inlet/outlet for common fuel hose sizes; includes hose clamps for a secure fit.
• Two bolt mounting pattern for stable installation on brackets or frames.

What performance should I expect from a 4–7 PSI pump?

This low-pressure range is suited for carburetor-fed engines and fuel transfer tasks where gentle, steady flow is required. The 4–7 PSI (0.028–0.048 MPa) output provides consistent delivery without overwhelming small fuel systems.

• Nominal pressure: 4–7 PSI, ideal for carburetors and gravity-return systems.
• Rated current ~2A at 12V for efficient, low-draw operation.
• Quiet, low-vibration function for reduced noise in small vehicles and equipment.

What’s included and how do the filters and clamps help?

The kit includes two pumps plus two inline fuel filters and eight hose clamps so you have everything needed for immediate installation or replacement. Filters trap particulates and sediment, protecting carburetors and fuel system components from wear and clogging.

• Package: 2 x HEP-02A pumps, 2 x transparent inline filters with orange element, 8 x hose clamps.
• Transparent filter body shows contamination level; metal end caps add durability.
• Clamps secure 5/16" fuel hoses to pump barbs to prevent leaks under pressure.

How simple is installation and maintenance?

Set-up is straightforward: cut the existing fuel line, slip on the hose clamps and filter, connect the pump’s 5/16" fittings, and wire the two pump leads to a 12V source with appropriate switching or fuse protection. Maintenance is minimal—periodically inspect the filter and replace it if clogged.

• Two-wire design: one positive and one negative lead for direct 12V connection.
• Transparent filter allows quick visual checks without disassembly.
• Lightweight copper-clad aluminum housing resists corrosion while remaining easy to handle.

Who is this for: The Threlaco 2-pack electric fuel pump kit is intended for DIY mechanics, small-engine repair shops, boat owners, and anyone who maintains carbureted equipment and needs reliable, low-pressure fuel delivery or a ready spare. It’s especially useful if you want a compact, easy-to-install inline pump with replacement filters and clamps included.
