CarBole External In-Line Fuel Pump — 12V High-Pressure 116 PSI, Universal Replacement (Red) with Mounting Kit

CarBole External In-Line Fuel Pump is a universal 12V high-pressure replacement pump (up to 116 PSI) designed for aftermarket fuel injection systems and turbo/non-turbo engines up to ~250 bhp.

This compact external pump delivers high flow and elevated pressure for upgraded or replacement fuel delivery setups. Built with reinforced injection-molded components, it resists corrosion and is intended for use outside the fuel tank. The unit arrives with a mounting clamp, connection covers, terminals, gaskets and hardware so you can adapt it to many applications; some vehicles will require custom fittings or wiring know-how for a safe installation.

What pressure and flow can I expect from this pump?

The CarBole pump operates across a high-pressure band suitable for many performance fuel injection applications. Nominal working pressure ranges from roughly 5–8 bar (about 72.5–116 psi), with measured flow rates decreasing as pressure rises.

• Typical flow: ~120 LPH at 6.0 bar (≈31.7 GPH at ~87 psi)
• Typical flow: ~100 LPH at 7.0 bar (≈26.4 GPH at ~101.5 psi)
• Max recommended pressure: ~8 bar (≈116 psi) for demanding injection systems

Which vehicles and systems will this pump work with?

This pump is a universal external in-line design intended for aftermarket fuel delivery or as a replacement where in-tank mounting is not required. It can serve turbocharged and naturally aspirated petrol systems up to approximately 250 bhp, but it is not an OEM-specific in-tank unit.

• Replaces common aftermarket part numbers including 0580464070 equivalents (not an OEM direct factory part)
• Best for high-flow aftermarket conversions, standalone systems and performance upgrades
• May need adapters, fittings or bracket modifications to match your vehicle’s plumbing

How do I install and wire this external fuel pump safely?

Installation requires basic mechanical skills and correct electrical wiring to ensure reliable operation and safety. The pump comes with a mounting clamp, insulated terminals and hardware, but the installer should provide compatible hoses, clamps and a proper fuse or relay rated for fuel-pump current draw.

• Mount outside the tank on a solid bracket using the supplied clamp and bolt
• Use fuel-rated hose and secure clamps; check flow direction stamped on the housing
• Wire through a dedicated relay and in-line fuse sized to the pump’s amperage

What fuel types and maintenance considerations apply?

Use only approved fuels — gasoline or diesel — and avoid fuels with high alcohol or methanol content. The pump is not suitable for liquids like water or fuels containing more than 15% methanol/ethanol blends; using improper liquids will damage the unit and void safe operation.

• Approved: gasoline and diesel only
• Not approved: fuels containing >15% methanol/ethanol, water or non-fuel liquids
• Periodic checks: inspect fittings, electrical connections and rubber seals for leaks or wear

Who is this for? CarBole’s external in-line fuel pump is aimed at do-it-yourself mechanics, tuners and installers who need a robust, high-pressure replacement for aftermarket fuel injection systems. It suits performance enthusiasts upgrading fuel delivery for engines up to roughly 250 bhp, garages fitting standalone systems, and anyone who prefers an external pump over an in-tank option. Note: installation may require custom plumbing and wiring skill; this product is supplied with mounting hardware but no step-by-step instructions.
