YONEDA Electric Fuel Pump Kit HEP02A 12V 2.5-4 PSI — 2m 5/16" Fuel Line, Filters & 10 Clamps

YONEDA's HEP02A electric fuel pump kit is a compact 12V pump with 2.5–4 PSI output, supplied with 2 meters of 5/16" fuel line, fuel filters and 10 hose clamps for quick installation on carbureted engines.

This kit is built to replace or upgrade mechanical fuel delivery on small engines such as lawn mowers, generators, boats and classic cars with carburetors. The pump features 8mm inlet and outlet ports with internal check valving to prevent backflow, and the included NBR hose, filters and clamps give you a ready-to-install system for steady fuel flow. The assembly is designed for basic DIY installation and works with any 12V electrical system delivering reliable low-pressure fuel feed where a simple, compact electric pump is needed.

How does this pump improve fuel delivery for carbureted engines?

The HEP02A supplies a consistent low-pressure feed (2.5–4 PSI) ideal for carburetors and small engines that don’t require high-pressure injection. Internal check valves prevent reverse flow when the pump stops, reducing priming issues and fuel loss. Strong suction characteristics help maintain steady supply even when mounting location is lower than the tank.

• Stable 2.5–4 PSI output suitable for most carbureted systems
• 8mm inlet/outlet ports match the supplied 5/16" (8mm) hose
• Internal valving prevents backflow and keeps the carburetor primed
• Strong suction reduces vapor lock and starvation risk in small engine setups

What components are included and how do they help installation?

The kit contains the electric pump, 2 meters (6.56 feet) of NBR fuel hose (5/16" ID), inline fuel filters and ten hose clamps so you can complete one or multiple connections without buying extras. Using matched-size fittings reduces leaks and keeps installation straightforward for hobbyists and mechanics alike. The clamps and filters protect the carburetor from debris and ensure a tight, sealed fuel line.

• 2 m of 5/16" ID NBR fuel hose for flexible routing
• Inline fuel filters to block contaminants and prolong carburetor life
• Ten hose clamps for secure, leak-free connections
• Standard 8mm pump ports for direct fit to supplied hose

Will this pump work with my 12V mower, generator or boat?

Yes—this pump is designed for compatibility with any 12V electrical system powering carbureted engines, small boats, generators, trucks and lawn equipment. It is not intended for high-pressure fuel injection systems or diesel common-rail applications. Check that your engine accepts low-pressure feed (2.5–4 PSI) and that the 5/16" hose diameter suits your fittings before installation.

• Compatible with 12V carbureted engines and small machines
• Not suitable for high-pressure injection systems
• Confirm hose ID (5/16") fits your engine fittings
• Ideal for conversions, replacements, and auxiliary fuel lines

How should I mount and maintain the pump for best performance?

Mount the pump close to the fuel tank but above the carburetor if possible, using rubber isolators to reduce vibration. Ensure firm hose connections with the supplied clamps and replace inline filters periodically to prevent blockages. Regular inspection for cracks, hardening of the NBR hose, and secure electrical connections will keep the pump operating reliably.

• Mount sturdy and vibration-isolated near the fuel source
• Use all supplied clamps for leak-free hose fittings
• Replace fuel filters on schedule to avoid clogging
• Inspect hose and electrical terminals for wear or corrosion

Who is this for: This YONEDA HEP02A kit is aimed at DIY mechanics, small-engine repair shops and owners of lawn mowers, portable generators, small boats or classic vehicles with carburetors who need a compact, low-pressure electric pump. It suits anyone looking for a straightforward replacement or auxiliary fuel feed solution that includes matching hose, clamps and filtration for a quick, reliable installation.
