The Fuel Injection Depot Dual Pump Plug & Play Returnless Fuel System is designed specifically for 2015-2023 Dodge Challenger and Charger Hellcat models equipped with the 6.2L Supercharged Gen 3 HEMI, providing increased fuel delivery for modified and high-horsepower combinations. The system comes standard with two high-flow Walbro 525 LPH pumps, also identified as Walbro/TI Automotive 285 pumps, along with a complete plug-and-play wiring harness, one additional FPDM, and an exclusive FPDM and harness mounting bracket for a clean, factory-like installation. Fuel Injection Depot designed the fuel hat to accommodate up to three pumps, allowing owners to start with the dual-pump configuration and add a third pump later as their power goals increase. The same modular fuel hat can also be retained when moving to one of Fuel Injection Depot’s return-style configurations, giving Hellcat owners an upgrade path without requiring them to replace the entire fuel hat. For supercharged Gen 3 HEMI builds that have outgrown the factory fuel system, this package provides a purpose-built solution that combines increased capacity, modularity, and straightforward installation.

Here’s what you’re getting in this ready-to-go package:

• A complete Plug and Play wiring harness (because who has time for complicated wiring nightmares? Not you).
• Two Walbro 525 LPH pumps that’ll fuel your Hellcat’s thirst for power.
• One FPDM (Fuel Pump Driver Module), because even fuel pumps need a little TLC.
• An FPDM mounting bracket (because we like to make sure everything is securely in place, no loose ends here).

Fuel demand rises quickly when modifying a Hellcat. Smaller supercharger pulleys, ported blowers, larger superchargers, camshaft upgrades, increased boost, larger injectors, ethanol-based fuels, and other performance modifications can push the factory fuel system beyond its intended operating range. Supplying adequate fuel under load is critical for maintaining commanded air/fuel ratios and supporting a properly calibrated high-performance engine.

The Fuel Injection Depot system retains a returnless configuration, making it an attractive option for owners who need additional fuel capacity without immediately converting the entire vehicle to a return-style system. Its plug-and-play wiring approach also helps simplify installation compared with building a custom fuel pump electrical system from individual components.

Modularity is one of the system’s biggest advantages. Every fuel hat is three-pump ready, so a third pump can be added without sending the hat back for modification. Fuel Injection Depot also offers a 295 pump upgrade and an optional third 295 TI fuel pump, controller, and plug-and-play harness for combinations requiring additional capacity. The manufacturer states that its modular systems can eventually be expanded with a fuel line kit for combinations in the 1,600 to 1,800 wheel-horsepower range, depending on injectors and power-adder selection.

Fitment is intentionally specific. This system is designed for 2015-2023 6.2L Hellcat Challenger and Charger models only. Fuel Injection Depot specifically states that it is not compatible with Redeye, Demon, Super Stock, Trackhawk, Durango, or 5.7L, 6.1L, and 6.4L HEMI applications.

For Hellcat owners planning additional boost, ethanol fuel, larger injectors, or a more aggressive power package, the Fuel Injection Depot Dual Pump System provides a scalable foundation. Its combination of dual 525 LPH pumps, plug-and-play installation, three-pump-ready construction, and future return-style compatibility makes it a strong option for building a fuel system that can grow alongside the car.
