CarBole 12V Micro Inline Fuel Pump E8012S — 5–9 PSI Low-Pressure, 30 GPH, 5/16" Fittings

The CarBole E8012S is a compact 12V inline micro fuel pump that delivers steady low-pressure fuel flow (5–9 PSI) at 30 GPH for gasoline and diesel automotive and marine systems.

Designed for universal fitment and reliable everyday operation, this CarBole micro electric fuel pump suits cars, trucks, boats and light industrial equipment that require a low-pressure inline unit. It replaces common cross-references such as E8012S, FD0002, P60430, EP12S and 6414671 and is intended for use with gasoline or diesel fuels (no alcohol blends). Quiet-running with a long service interval when paired with proper filtration, the pump provides a compact solution for fuel delivery in retrofit and repair projects.

How does the CarBole pump perform in typical vehicle applications?

The CarBole E8012S produces a consistent 30 gallons per hour flow while maintaining 5–9 PSI output pressure, suitable for carbureted systems, returnless EFI setups that need low pressure, and many auxiliary fuel installations. Its compact inline form allows flexible mounting close to the fuel line to shorten runs and reduce complexity.

• Flow rate: 30 GPH for steady delivery during normal operation
• Pressure range: 5–9 PSI, compatible with low-pressure fuel systems
• Voltage: 12V DC for standard automotive electrical systems
• Cross-references: E8012S, FD0002, P60430, EP12S, 6414671 for easy replacement

What installation and compatibility details should I consider?

The pump uses 5/16-inch hose fittings and fits inline with existing fuel lines; use a quality fuel filter upstream to protect the pump from debris. It is built for gasoline and diesel only—avoid alcohol-containing fuels—and requires a proper 12V supply with fused wiring and secure mounting to limit vibration and extend service life.

• Inlet/outlet size: 5/16 inch hose for standard fuel lines
• Electrical: 12V input, use appropriate gauge wire and a fuse
• Mounting: clamp or bracket mounting to reduce vibration and noise
• Filtration: always install a fuel filter before the pump to prevent damage

How quiet and durable is this micro fuel pump?

CarBole designed the E8012S for quiet operation and steady flow over extended mileage when correctly installed and filtered. While it’s compact, the pump is rated for continuous use in automotive and some marine settings, offering dependable delivery without excessive noise when mounted securely.

• Operation: engineered for low-noise performance in normal installations
• Longevity: steady flow performance expected with proper filtration
• Applications: suitable for cars, light trucks, boats and industrial uses

What safety and maintenance steps are recommended?

To keep the pump functioning reliably, always fit a fuel filter upstream, check electrical connections for corrosion, and secure the unit to minimize movement. Avoid using fuels containing alcohol, and inspect the pump and hoses periodically for leaks or wear.

• Use a fuel filter to protect the pump from particulates
• Regularly inspect hoses, clamps and electrical terminals
• Do not run on alcohol-containing fuels; designed for gasoline and diesel only

Who is this for: The CarBole E8012S micro electric fuel pump is aimed at DIY mechanics, restoration specialists, and fleet or marine technicians who need an economical, compact inline pump for low-pressure fuel systems. It’s a practical replacement or upgrade for vehicles and equipment that require a 12V, 5–9 PSI pump delivering about 30 GPH, provided it’s matched with compatible fuel types and proper filtration.
