APR Tuning Stage 3 Fuel System Upgrade | Various Models (MS100111) APR Tuning

Performance Stage 3 Fueling System for Various Models by APR Tuning

The APR Fueling System is a comprehensive upgrade required to safely support Stage 3+ power levels. The upgrade includes a larger in-tank low pressure fuel pump (LPFP) and adds multi-port injection (MPI) to the factory manifold on North American vehicles. Both upgrades are ethanol compatible. All necessary hardware is included for a seamless integration and the system is fully controlled by the factory engine control unit (ECU) thanks to APR’s ECU Upgrade.

The 2.0T Ea888 Gen 3 engine uses a returnless, pulse width modulated (PWM) controlled, in-tank low pressure fuel pump that feeds a cam-driven high pressure fuel pump (HPFP), and gasoline direct injection (GDI) injectors. Some models also include multi-port injection (MPI) injectors, which are only used for emissions reasons under light driving. The factory fueling system maxes out at below APR Stage III+ power levels before headroom for safety and longevity decreases dramatically.

To support higher power levels, the APR Fueling system upgrades several components. First the LPFP is upgraded to a larger, 305 LPH ethanol-compatible unit, mounted inside the factory fuel basket with the included APR mounting hardware. At its inception, the pump is the largest readily available pump of its kind, both physically compatible with the factory fuel basket, and fully compatible with the factory PWM fuel pump controller without additional controllers.

Features

• More Fuel and More Power: Provides the required fueling to support APR Stage 3+ power levels.
• 980 CC Bosch Motorsport MPI Injectors: Converts the factory injection system to a true, dual, MPI and GDI setup, with large enough injectors to support power levels well beyond APR Stage 3+ power levels for North American Vehicles.
• 305 LPH High Flow In-Tank Fuel Pump: Upgrades the LPFP to the largest readily available pump compatible with the factory fuel basket, and PWM controller without additional controllers.
• Proper MPI/GDI Fuel Distribution: The fuel distribution block ensures fuel is properly delivered to the both sets of injectors on North American vehicles.
• Ethanol Compatible Hardware: Fully Ethanol / E85 compatible injectors, fuel pump and associated hardware.
