CarBole Micro Electric Petrol Fuel Pump 12V 5/16" Inlet/Outlet 35 GPH, 4–7 PSI for Carbureted Engines

CarBole Micro Electric Gasoline Fuel Pump is a compact 12V, 1–2A inline pump delivering 35 GPH at 4–7 PSI for carbureted engines with 5/16" inlet and outlet fittings.

This compact pump is built to transfer gasoline and feed carburetor-equipped engines in many domestic vehicles. It’s optimized for low-volume flow where modest pressure and steady delivery matter. Because it’s designed for carburetor systems, it is not suitable for modern high-pressure fuel-injected engines. The pump’s universal 5/16" inlet/outlet and modest electrical draw make it an easy replacement or auxiliary pump for older cars, small engines, and fuel-transfer tasks.

How will this pump fit my vehicle or project?

The CarBole Micro pump uses standard 5/16" (≈8 mm) inlet and outlet ports that adapt to common fuel hose sizes, and its universal design targets most domestic 4-, 6- and 8-cylinder carbureted engines. Confirm your engine is carbureted and not fuel-injected before installing. Wiring is straightforward: a 12V supply with a 1–2A draw works fine for regular operation.

• 5/16" inlet and outlet for typical fuel hoses
• Universal fit for many Toyota, Ford, Honda, Mazda carburetor vehicles
• 12V electrical supply with 1–2A current consumption
• Not compatible with fuel-injected high-pressure systems

What performance can I expect during use?

This pump provides about 35 gallons per hour flow and maintains operating pressure in the 4–7 PSI range, enough for carburetor feed and small fuel-transfer tasks. It offers steady, low-pressure delivery rather than the higher pressures used by injectors. Expect efficient operation for light-duty applications and hobby or restoration projects.

• Flow rate: approximately 35 GPH for quick transfers
• Operating pressure: typically 4–7 PSI for carburetor systems
• Electrical draw: low, between 1 and 2 amps at 12V
• Best for continuous light-duty use rather than heavy industrial cycles

How do I install and maintain the pump safely?

Installation is straightforward: mount the pump securely, connect fuel hoses to the 5/16" fittings, and wire to a fused 12V source with correct polarity. Position the pump below or near the tank when possible to reduce strain and vapor lock. Routine inspection of hoses, clamps, and electrical connections helps prevent leaks and ensures reliable operation.

• Mount securely to reduce vibration and wear
• Use fuel-rated hose clamps and replace worn lines
• Wire to a fused 12V circuit and observe correct polarity
• Check for leaks and clean or replace filters as needed

Can this pump be used for fuel transfer tasks?

Yes — the pump’s 35 GPH flow and moderate pressure make it effective for moving gasoline between tanks, filling small containers, or priming carburetor bowls. Use in a well-ventilated area and follow fuel-handling safety practices. It’s not intended for continuous industrial pumping but handles light transfer duties well.

• Effective for gasoline transfer and priming carburetors
• Quickly moves fuel at 35 GPH for small to medium tasks
• Handle outdoors or in ventilated spaces to avoid vapors
• Not suitable for diesel-specific or pressurized injector systems

Who is this for: The CarBole Micro Electric Gasoline Fuel Pump is aimed at car enthusiasts restoring older domestic vehicles, DIY mechanics needing a reliable carburetor feed or transfer pump, and hobbyists working with small gasoline engines. It’s a practical choice if you need a compact, low-draw, universal inline pump for carbureted systems or occasional fuel transfer. Avoid this unit if your vehicle uses a high-pressure fuel-injection system; instead, choose a pump specified for injection applications.
