Threlaco 2 Pcs Electric Fuel Pump Kit 12v Universal Low

Threlaco's 2-piece 12V inline electric fuel pump kit supplies low-pressure fuel delivery (4–7 psi) for carbureted engines and small equipment, packaged with two disposable fuel filters and eight hose clamps for an out-of-the-box replacement.

This compact kit is built for straightforward fuel-system repairs and upgrades on a wide range of 12-volt machines — from lawn mowers, generators, and boats to older cars and trucks that use carburetors. Each pump uses copper-clad aluminum internals and a transparent housing so you can monitor flow, while included filters and clamps ensure a clean, secure installation without sourcing extra parts.

How does this pump work in low-pressure fuel systems?

The Threlaco inline pump provides continuous, low-pressure flow suited to carburetors and gravity-feed systems. It runs on 12 V and produces an output pressure between 4 and 7 psi, enough to feed small engines reliably without overpressurizing float systems.

• Rated output: 4–7 psi (0.028–0.048 MPa)
• Operating current: approx. 2 A at 12 V
• Inline design fits standard 5/16" fuel hoses and connectors
• Quiet operation and lightweight housings for easy mounting

What is included and how do I install the kit?

The kit includes two electric pumps, two inline fuel filters, and eight hose clamps so you have everything needed for two installations or a spare. Installation is direct: secure the pump with two bolts, connect the fuel lines to the 5/16" fittings, and wire the two leads to the 12 V supply with proper polarity and a fuse.

• 2 x Threlaco HEP-02A pumps (12 V, copper-clad aluminum internals)
• 2 x transparent inline fuel filters with brass end caps
• 8 x stainless hose clamps sized for 5/16" fuel line
• Mount via two-bolt pattern; wire with inline fuse for protection

Which engines and vehicles are compatible?

These pumps are intended for 12 V systems that require low-pressure fueling. They pair well with carbureted engines, small outboard motors, lawn and garden equipment, portable generators, and many classic or off-road vehicles that do not use high-pressure EFI systems.

• Carburetor-equipped cars and trucks (12 V)
• Lawn mowers, garden tractors, and small engine equipment
• Boats and portable generators with 12 V electrical systems
• Not suitable for high-pressure fuel injection systems

Who is this for? The Threlaco 2-piece electric fuel pump kit is designed for DIY mechanics, small engine repair shops, and boat or off-grid equipment owners who need a dependable, low-pressure replacement or backup pump. If you operate carbureted engines or simple gravity-feed systems and prefer a kit that includes filters and clamps for a tidy, fast installation, this offers a practical, cost-effective option. For vehicles with high-pressure fuel injection, consult manufacturer specifications and choose an appropriate EFI pump instead.
