Racetronix QFPS-F99-2100 incorporates it's patented pump interlock technology which allows for multiple pumps to be installed in a factory tank without modification required. This 'building a ship in a bottle' approach allows for installation of up to four pumps thereby supporting outlandish flow capabilities and horsepower levels. All this performance is packed into a simplistic design which can be installed and managed with moderate technical skills. Every part of the in-tank pump module has been engineered to be as ergonomic as possible using the highest quality components. Billet anodized 6061-T6 aluminum and 304 stainless steel are used throughout the assembly. Superior Viton (FKM) GF-600S seals are incorporated for extra durability over standard Viton (FKM) when used with Ethanol and oxygenated race fuels.

The entire wiring system is 100% plug & play with the factory harness and interfacing to optional aftermarket engine management systems may be done easily. The fuel pump's in-tank Teflon wiring is upgraded to improve pump performance. A 6-position electrical bulkhead connector provides dedicated power to each of the four pumps. High-current electrical connectors which fuel-safe fluorosilicone seals are used to enhance contact reliability. There is dedicated 10-gauge wiring for each of the four pump circuits. Each circuit utilizes a dedicated 630-series 40-amp rated relay and fuse holder. Each circuit can be controlled independently for staged operation. Four ground control jumpers control primary and staged boost-controlled pump activation via pressure switches or pull to ground outputs from a PCM.

For applications involving forced induction, the QFPS-F99-2100 configuration is engineered to provide the absolute maximum in fueling overhead. When utilizing standard gasoline, this quad-pump system is projected to support upwards of 2,500 RWHP. For users running E85/Ethanol blends, which require significantly more fuel volume, the system is projected to support upwards of 2,000 HP. These figures assume the use of properly sized fuel lines and high-flow components as outlined in the requirements section below.
