Product Description
The BOSCH High-Pressure Electric Fuel Pump (0 580 464 126)—internally designated as the EKP-3-D—is a legendary external "inline" fuel pump designed for high-performance fuel-injected engines. Unlike modern in-tank pumps, this unit is engineered to be mounted externally along the chassis fuel lines. Its primary operational function is to draw fuel from the reservoir and pressurize it to a high operational baseline (up to 6.5 bar) required for precise fuel atomization in mechanical (K-Jetronic) and early electronic fuel injection systems. Its robust, metal-housed design and high-flow capability make it the industry standard for restoring classic fuel-injected European performance vehicles.

⚠️ Essential Technical Warnings:
- Cooling & Mounting: As an external pump, this unit relies entirely on the flow of fuel moving through it for internal lubrication and cooling. Never operate this pump "dry" for testing purposes, or the internal pump impeller will seize within seconds. Mount it vertically or horizontally according to the vehicle's original orientation to prevent air pockets.
- Fuel Filter Pre-Screening: This pump is highly sensitive to debris. If you are replacing a failed pump, you must replace the fuel tank strainer and the main inline fuel filter simultaneously. If a single particle of rust enters the 0 580 464 126, it will score the internal pump vanes and cause it to fail prematurely.
- Safety Relay: This pump must only receive power when the engine is cranking or running. Ensure your fuel pump relay circuit is functioning correctly so the pump does not remain pressurized when the ignition is simply turned to the "ON" position without the engine starting.
