APR Low Pressure Fuel Pump

The APR Low Pressure Fuel Pump (LPFP) upgrade, also called an auxiliary fuel pump or low pressure fueling system, helps the low pressure fueling system deliver enough fuel from the tank to the high pressure fuel pump (HPFP). It is built for high-demand, high-horsepower situations where the factory system can fall short.

The factory pump sits in a basket inside the fuel tank and is driven by a pulse-width modulated (PWM) signal. Upgrading it is not a simple drop-in job. Space is limited, and higher-output pump controllers can overheat or depend on signals that these vehicles don't supply. APR's approach is an inline pump that works alongside the factory pump. A dedicated controller manages it.

Key Features:

• 255 LPH high-flow inline fuel pump with mounting bracket
• APR auxiliary ECU and harness that connect to the factory CAN bus and receive operating data from the factory ECU
• The pump runs only when fueling demand calls for it, which means quiet, cool, low-power operation
• OEM-quality fuel lines, crimp clamps and quick connectors
• Direct bolt-on installation that needs no ECU software
• Fuel tank emptying mode for switching fuel grades or for dry storage and transportation
• Supports higher-output calibrations with select APR Stage 3/3+ turbocharger systems
• Only needed where specified by APR

Each variant in this product line is a complete, clean upgrade made by APR for supporting high-output tuning. Choose the variant that matches your drivetrain and engine.
