APR Fueling System Upgrade
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, both of which 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.
