RUIDELI 12V Low-Pressure Inline Fuel Pump Kit — 70 L/h Flow, 2.5–4 PSI, 10 ft Hose & Filters

RUIDELI's 12-volt low-pressure inline fuel pump is a compact electric pump kit engineered to deliver steady fuel flow (70 L/h) at 2.5–4 PSI for carbureted engines, small boats, lawn equipment and DIY fuel-system repairs.

This ready-to-install set includes a pure-copper plunger-style pump, a 10-foot 5/16" (8mm) NBR fuel line, two in-line filters, two shut-off valves and 15 clamps—designed to be durable, oil- and ethanol-resistant, and suitable across a wide temperature range. The pump’s built-in check valve prevents backflow and the plunger mechanism improves suction and steady fuel delivery for low-pressure applications.

How reliable is this pump for everyday small-engine use?

The pump is built with a 100% copper motor and a plunger-style feed to strengthen suction and keep delivery steady at low pressures (2.5–4 PSI). It’s intended for intermittent or continuous use on low-pressure fuel systems where gentle, consistent flow matters more than high pressure.

• Rated flow: 70 L/h—suitable for carburetors and small engines
• Designed output pressure: 2.5–4 PSI for safe low-pressure operation
• Built-in check valve prevents fuel backflow when power is off
• 100% copper construction for better conductivity and longevity

Which vehicles and equipment will this pump work with?

This universal 12V unit is compatible with most 12-volt systems, making it useful for cars, trucks, ATVs, boats, lawnmowers and portable generators that use low-pressure fuel delivery or carbureted setups.

• Suitable for 12V electrical systems found on common cars and trucks
• Works on marine outboards and inboard engines with low-pressure feeds
• Ideal for lawn and garden equipment, small engines, and generators
• Supports fuels including gasoline blends (E10, E85), diesel, and many lubricants

What does the kit include and how does that simplify installation?

The kit bundles the pump with the essential hoses, filters and fittings so you won’t need to source multiple parts. That helps DIYers and mechanics complete repairs or upgrades with a single purchase.

• 1 × 12V low-pressure fuel pump with built-in check valve
• 1 × 10 ft (5/16" / 8mm) NBR fuel hose rated for oil and ethanol resistance
• 2 × inline fuel filters and 2 × shut-off valves for isolation and service
• 15 × hose clamps for secure connections and leak prevention

How durable is the fuel line and what fuels can it handle?

The supplied 5/16" NBR fuel hose is constructed with nitrile inner layers and a high-strength synthetic outer braid for resilience against oil, ethanol and general wear. It meets common industry testing standards and performs across a wide temperature range.

• Materials: nitrile inner tube and interlayer, synthetic high-strength outer braid
• Temperature range: -30°C to 100°C for varied climates and storage
• Fuel compatibility: gasoline (including E10/E85), diesel, antifreeze, lubricants
• Tested standards and adhesive strength to resist cracking, aging and ozone

Who this is for: This RUIDELI pump kit suits DIY mechanics, hobbyists, small-fleet technicians and boat owners needing a dependable, low-pressure feed solution. If you maintain carbureted engines, run auxiliary tanks, or want a compact inline pump for testing and temporary setups, this kit delivers the essential parts and reliability for low-pressure fuel delivery.
