PRUNkuar Universal 12V Electric Fuel Pump Kit — 5/16" Inline, 3–6 PSI, Reinforced Hose & Stainless Clamps

PRUNkuar's Universal Electric Fuel Pump Kit is a compact 12V in-line transfer pump delivering 3–6 PSI and 80–100 L/h, supplied with reinforced hose, fuel filter, and stainless clamps for a ready-to-install fuel delivery upgrade.

This kit combines a small, transparent-bodied DC fuel pump with a reinforced fuel line, inline filter, and ten 304 stainless-steel clamps so you can replace or add a reliable fuel feed on cars, small trucks, boats, generators, or lawn equipment. The pump's copper-clad aluminum construction and brass end caps provide corrosion-resistant contact points, while the visible orange inner filter helps you spot contamination at a glance. The package is designed for straightforward inline installation on 5/16" (8 mm) fuel lines and supports common 12V systems.

How does this pump fit into my vehicle's fuel system?

The PRUNkuar pump is an in-line transfer pump made to connect directly to 5/16" fuel tubing, replacing or supplementing low-pressure fuel feeds. It mounts inline between the tank and the carburetor or fuel rail, keeping installation simple without extensive modifications.

• Compatible with 5/16" (approx. 8 mm) fuel lines and fittings
• Direct inline placement between tank and engine fuel inlet
• Transparent body lets you inspect fluid and filter condition
• Includes stainless clamps and a 5/16" filter for secure connections

What performance can I expect from the 12V 3–6 PSI pump?

This DC pump is rated for 3–6 PSI (0.032–0.045 MPa) and will deliver roughly 80–100 liters per hour, making it suitable for low-pressure fuel delivery tasks. The specified flow and pressure are ideal for gravity-fed or carbureted systems and many small engines where high-pressure fuel systems are not required.

• Flow: about 80–100 L/h for steady supply
• Pressure range: 3–6 PSI for low-pressure applications
• Operates on standard 12V vehicle electrical systems at ~2A draw
• Strong oil absorption design reduces air entrainment during transfer

What materials and components are included, and why do they matter?

The pump features a copper-clad aluminum body with brass end caps and a visible orange inner filter, balancing corrosion resistance with light weight. The included fuel hose has a reinforced three-layer construction and the clamps are 304 stainless steel for long-lasting, rust-resistant connections.

• Pump model HEP-02A: copper-clad aluminum and brass end caps
• Reinforced fuel pipe: rubber inner/outer, nylon-fiber middle layer, 3.2 mm wall
• Inline 5/16" filter with transparent housing to catch debris
• Ten 304 stainless-steel hose clamps for durable seals

Is this kit compatible with my equipment and how easy is installation?

The kit is made for universal 12V systems and fits many common makes and small engines; it is especially suited to older cars, small trucks, boats, generators, and lawnmowers that accept low-pressure pumps. Installation is intended to be direct and straightforward for anyone comfortable with basic fuel-line work, but follow safety practices for fuel-handling and wiring.

• Designed for 12V systems in many Toyota, Ford, Honda, Mazda models and similar vehicles
• Also fits marine engines, portable generators, and lawn equipment with 5/16" lines
• Plug-and-clamp style hose connections — basic hand tools required
• Observe fuel-safety and wiring best practices during installation

Who is this for: The PRUNkuar Universal Electric Fuel Pump Kit is intended for mechanics, DIYers, fleet technicians, and hobbyists who need a compact, low-pressure fuel pump to replace or augment fuel delivery on 12V equipment. It suits owners of older carbureted vehicles, small boat operators, landscapers maintaining mowers, and anyone who wants a clear-bodied pump and durable hose/clamp hardware for reliable, visible fuel transfer. If you require a high-pressure EFI pump, this low-pressure transfer pump is not the right choice.
