Threlaco 12V Electric Fuel Pump Kit 2-Pack (Gold) — Universal 4–7 psi, Includes Inline Filters & Clamps

Threlaco’s 2-piece 12V electric fuel pump kit supplies reliable low-pressure fuel delivery for carbureted engines, small motors, and auxiliary applications.

This compact kit bundles two universal 12-volt electric fuel pumps rated at 4–7 psi with inline fuel filters and mounting hardware, so you get a ready-to-install solution for cars, trucks, boats, lawn mowers and generators. Built with copper-clad aluminum and a transparent housing on the filter, the pumps are lightweight and quiet and fit standard 5/16" fuel lines for straightforward replacement or retrofit installs.

What does the kit include and why does that matter?

The package contains two 12V (model HEP-02A) electric fuel pumps, two inline fuel filters and eight hose clamps. Including filters and clamps means you have all essential components required to connect the pumps to existing fuel lines and protect the system from debris.

• Two HEP-02A electric fuel pumps (12V, 2A) delivering 4–7 psi output pressure.
• Two transparent inline fuel filters with orange inner screens and brass end caps.
• Eight hose clamps sized for 5/16" fuel line connections for secure fittings.
• Two-wire design and two bolt fixing for simple mounting and electrical hookup.

How will these pumps fit my vehicle or equipment?

Each pump is built for universal compatibility with 12-volt carbureted systems and small engines. The ports fit 5/16" fuel hoses and common connectors, so you can swap them into many cars, trucks, boats, lawn mowers, generators and other 12V devices without major modifications.

• Standard 5/16" inlet/outlet for easy integration with existing lines.
• Suitable for gas and diesel in low-pressure applications like carburetors.
• Compact dimensions and two-bolt mounting make placement flexible.
• Quiet operation and low current draw (about 2A) for efficient use.

What performance and construction features should I expect?

The pumps use copper-clad aluminum components to reduce weight while maintaining conductivity and heat management. Output pressure ranges between 4 and 7 psi (0.028–0.048 MPa), making them appropriate for gravity-fed and low-pressure fuel systems rather than high-pressure fuel injection setups.

• Output pressure: 4–7 psi, ideal for carbureted or auxiliary fuel delivery.
• Material: copper-clad aluminum for a balance of strength and lightness.
• Transparent filter housing to visually monitor contamination and sediment.
• Minimal noise in operation for discreet installation on vehicles or equipment.

How easy is installation and routine maintenance?

Installation is straightforward: attach the 5/16" hoses, secure clamps, mount with two bolts and wire the two electrical leads to a 12V supply. The included inline filters simplify maintenance—replace the filter element when you observe dirt in the transparent casing or reduced flow.

• Two-wire electrical hookup; observe polarity for correct operation.
• Two-bolt mounting keeps the pump stable under normal vibration.
• Replaceable inline filters with metal brass end caps for longevity.
• Kits include extra clamps so you can tighten or replace fittings as needed.

Who is this for: This Threlaco kit suits DIY mechanics, fleet owners and hobbyists who need an economical, universal replacement or secondary fuel pump for carbureted engines and small gasoline or diesel equipment. It’s intended for low-pressure fuel systems where a compact, easy-to-install pump with visible filtration and quiet performance is required.
