CarBole 12V Gasoline Inline Fuel Pump 5/16" Inlet/Outlet — 28 GPH Low-Pressure, 2-Bolt Mount

The CarBole Gasoline Electric Fuel Pump is a compact 12V inline pump that delivers 28 GPH at 2–3.5 PSI with 5/16" inlet and outlet fittings, designed as a universal replacement for many cars, trucks, boats and generators.

This lightweight, inline fuel transfer pump replaces worn or weak pumps and supplies a steady low-pressure fuel flow for gasoline applications. Built with a two-wire hookup and a two-bolt mounting flange, it’s intended for straightforward installations where a simple, reliable fuel feed is needed. Note: engineered for gasoline only — avoid E85, ethanol, methanol, race fuels, and any water-containing liquids.

How does this pump fit into my vehicle or equipment?

The CarBole pump uses 5/16" (0.315") inlet and outlet ports and a two-bolt flange so it matches many common inline pump mounting arrangements. Because it operates at 12 V and draws 1–2 A, it pairs with typical automotive electrical systems and small engine setups. It’s commonly used as a replacement for domestic brands when the original specification matches.

• Inlet/outlet size: 5/16" (0.315") — works with standard fuel hose and clamps.
• Electrical: 12 V DC, 1–2 A draw — compatible with car or generator 12 V systems.
• Mounting: 2-bolt flange for stable attachment in many configurations.
• Flow & pressure: 28 GPH at 2–3.5 PSI for low-pressure fuel delivery.

What fuels and conditions is it suitable for?

This pump is built for gasoline applications only. It reliably moves petrol in low-pressure systems for everyday engines and small fuel transfer tasks, but it is not designed for fuels with high alcohol content or corrosive additives.

• Recommended: regular gasoline for cars, trucks, boats, generators.
• Not recommended: E85, ethanol, methanol, race fuel, or watery mixtures.
• Installation note: always use a fuel filter upstream of the pump to prevent debris damage.
• Temperature/environment: normal operating environments for automotive and marine use; avoid prolonged immersion.

How reliable and easy is installation and maintenance?

Installation is straightforward for anyone familiar with basic fuel-hose and electrical connections. The compact design and two-wire setup simplify replacement tasks, while routine checks of hoses, clamps, and the fuel filter help extend service life.

• Connections: two wires (positive/negative) — observe correct polarity.
• Service: check hose clamps and filter regularly to prevent clogs.
• Durability: designed for typical automotive duty cycles; avoid corrosive fuels.
• Replacement tip: match inlet/outlet size and mounting pattern to original pump.

What performance can I expect day-to-day?

Expect a consistent low-pressure fuel feed suitable for carbureted systems or low-pressure injection setups that require about 28 gallons per hour. The moderate 2–3.5 PSI operating pressure stabilizes fuel delivery without over-pressurizing lines designed for low-pressure operation.

• Flow rate: 28 GPH supports continuous low-pressure fuel supply.
• Pressure range: 2–3.5 PSI helps prevent fuel system stress in compatible engines.
• Power draw: modest 1–2 A consumption at 12 V reduces electrical load.
• Compatibility: suits many cars, trucks, boats, and small engine generators.

Who this is for: The CarBole universal inline gasoline pump is aimed at DIY mechanics, fleet maintenance crews, boat owners, and small-engine operators who need a compact, low-pressure fuel pump replacement. Choose this unit when your system requires a 12 V pump with 5/16" fittings and a modest 28 GPH flow, and ensure you pair it with the correct fuel filter and compatible fuel type.
