Threlaco 12V Electric Fuel Pump Kit, 2-Pc Gold — Universal 4–7 psi Inline Filters

Threlaco's 2-piece 12V electric fuel pump kit is a compact, low-pressure (4–7 psi) replacement set designed to supply gasoline or diesel to carbureted engines in cars, trucks, boats, mowers and generators.

This kit combines two universal inline electric pumps with inline filters and hose clamps to form a ready-to-install fuel delivery solution for 12V systems. Built with copper-clad aluminum internals and a transparent housing around an orange particulate filter, the pumps are intended for low-pressure applications where a steady, quiet flow is needed. The package includes everything required to connect to 5/16" fuel lines and mount the unit using the built-in bolt holes.

How will these pumps fit my vehicle or equipment?

Each pump is made to accept standard 5/16" fuel lines and comes with hose clamps and inline filters for a straightforward replacement or auxiliary installation. Two wires provide simple electrical hookup, and the pair of mounting bolt holes secures the unit in place.

• Fits 5/16" fuel tubing and 5/16" connectors
• Compatible with 12V carbureted engines, small boats, lawn mowers, generators, trucks and cars
• Includes 8 hose clamps for secure connections
• Two-bolt fixing points for stable mounting

What performance can I expect from a 12V, 4–7 psi pump?

These pumps are designed for low-pressure circulation and feed typical carburetor-based fuel systems reliably without high-pressure regulation. Expect quiet operation and modest current draw (around 2A), suitable for continuous or intermittent duty in small engine and auxiliary fuel applications.

• Output pressure range: 4–7 psi (0.028–0.048 MPa)
• Voltage: 12V DC, current approx. 2A
• Copper-clad aluminum internals for corrosion resistance and light weight
• Transparent case for visual inspection of the orange internal filter

How do the included filters and clamps improve longevity and safety?

The inline fuel filters remove sediment and limit particulate from entering carburetors or injectors, reducing wear and clogging. The metal hose clamps ensure leak-free connections under low pressure so the system remains stable during operation and storage.

• Inline orange filter traps impurities and visible sediment
• Metal brass end caps on filters for durable seals
• Eight hose clamps included to secure both pump ends and fuel lines
• Transparent shell aids quick visual checks for contamination

How easy is the kit to install and maintain?

Installation is straightforward: connect the 5/16" fuel hose, tighten clamps, and wire the two electrical leads to a switched 12V source. Maintenance is mostly visual and filter-based — replace filters and inspect clamps as part of routine service.

• Simple two-wire electrical connection — positive and ground
• Direct inline replacement without complex plumbing or regulators
• Lightweight and compact for tight engine bays or remote mounts
• Quiet running reduces noise when installed near operator compartments

Who is this for: This Threlaco 2-piece pump kit is aimed at DIY mechanics, small-boat owners, gardeners with ride-on mowers, fleet maintainers and anyone needing an economical, universal 12V low-pressure fuel pump solution. It's best used with carbureted engines and auxiliary fuel systems that accept 5/16" lines and require a simple, visible inline filter. Avoid using this kit where high-pressure fuel injection or manufacturer-specified pumps are required.
