CarBole 12V Low Pressure Inline Fuel Pump 2-3.5 PSI

The CarBole 12V low-pressure inline fuel pump is a compact electric fuel transfer unit delivering 2–3.5 PSI and about 24 GPH for carbureted engines, generators, and small marine and yard equipment.

This durable inline pump is designed as a universal replacement or booster to move fuel reliably where low pressure and steady flow are required. Built with a zinc housing and a copper-wound motor, it accepts common fuels (gasoline and diesel) and ships with a fuel filter and mounting hardware for quick installation. It matches several OEM cross-reference numbers and is tailored for 12-volt systems, making it a straightforward swap on many older or non-sequential fuel systems.

How does the CarBole pump perform in real-world use?

Expect a consistent low-pressure output suited to carburetors and auxiliary fuel systems. The pump produces roughly 2 to 3.5 PSI and about 24 gallons per hour, delivering steady flow without the high pressures required by fuel-injected systems.

• Output pressure: 2–3.5 PSI for stable carburetor feed
• Flow rate: approximately 24 GPH for effective transfer and priming
• Built-in check valve reduces backflow and maintains prime
• Designed for continuous and intermittent use as booster or replacement

Will this pump fit my vehicle or equipment?

The pump is intended for carbureted engines, generators, small boats, lawn tractors and other 12V systems that require low-pressure feed. It is not compatible with electronic fuel-injection systems which need higher pressure and specific pump designs.

• Voltage: 12-volt electrical systems only
• Hose connection: 5/16" (8 mm) fitting for standard low-pressure lines
• Cross-references: E8012S, FD0002, P60430, EP12S, 6414671 for many legacy applications
• Includes filter and mounting kit for easier retrofit

What materials and durability features does it include?

The housing uses a white zinc finish and the motor windings are copper, giving a balance of corrosion resistance and reliable electrical performance. The pump tolerates a wide operating temperature range to suit seasonal and varied-location usage.

• Construction: zinc housing with pure copper motor windings
• Temperature range: rated approximately -86°F to 158°F for broad environmental tolerance
• Internal check valve for anti-siphon protection and improved suction
• Engineered for resistance to vibration typical in vehicles and small equipment

Which fuels can I use with this pump and what should I avoid?

The pump works with conventional gasoline, pump gas, racing gas and diesel fuel; it is not suitable for fuels containing significant alcohol blends. Avoid use with E85, ethanol-rich gasoline or methanol, as these can degrade seals and shorten service life.

• Compatible: gasoline, pump gas, racing gas, diesel
• Not compatible: alcohol-containing fuels like E85 or high-ethanol blends
• Not for use on EFI systems—intended for carburetors and gravity/low-pressure feeds
• Regular inspection of supplied inline filter recommended for longevity

Who is this for: The CarBole 12V low-pressure inline pump is aimed at DIY mechanics, restoration enthusiasts, small boat owners, landscapers, and anyone needing a reliable replacement or auxiliary pump for carbureted engines and portable generators. If your system runs at low pressure and uses 12 volts, this pump offers an affordable, easy-to-install option; if you have an EFI vehicle or require higher pressure, look for a pump designed specifically for that application.
