DeatschWerks 09-15 Cadillac CTS-V DW300c Fuel Pumps The DeatschWerks 09-15 Cadillac CTS-V DW300c (2) 340 LPH In-Tank Fuel Pumps w/ Install Kit gives your CTS-V the fuel it needs for real power. Stock pumps struggle when boost and airflow go up. This dual DW300c setup feeds steady fuel at high load. It fits inside the factory tank and uses a complete install kit. No guessing. No weak links. Just reliable fuel delivery.Why These Pumps Matter More power needs more fuel. Many CTS-V owners learn this the hard way. The car feels strong until the fuel system hits its limit. The DW300c pumps remove that limit. They flow 340 liters per hour each. Together, they support big injectors, larger blowers, and aggressive tunes.I have seen cars gain consistency the same day these pumps go in. Throttle stays clean. Fuel pressure stays stable. The engine feels calm instead of stressed.Product Specifications – DeatschWerks 9-309-1039Vehicle Application: 2009–2015 Cadillac CTS-VPump Model: DeatschWerks DW300c (Dual Pump Setup)Fuel Pump Type: In-tank turbine-style electric pumpsFlow Rating: 340 LPH per pumpConfiguration: Twin in-tank pumps with vehicle-specific install kitOperating Voltage: 12–13.5 voltsFuel Compatibility: Gasoline, E10, E85 compatibleElectrical Connectors: Plug-and-play style connectors includedInternal Design: Compact turbine impeller for stable pressureKit Components:Dual DW300c pumpsWiring harness and connectorsFilters/strainersMounting hardwareInstallation Type: Fits inside factory CTS-V fuel moduleFeatures With Real BenefitsDual 340 LPH PumpsDelivers high fuel volume under boostSupports modified engines and larger injectorsKeeps pressure steady at wide open throttle Benefit: The car pulls hard without leaning out.Direct In-Tank FitWorks with factory fuel moduleNo external surge tank neededClean OEM-style install Benefit: Stock look with race-level flow.Complete Install KitCorrect wiring and connectorsProper filters and hardwareClear fit for CTS-V chassis Benefit: Less shop time and fewer mistakes.Proven DW300c DesignQuiet turbine operationReliable daily driving mannersTested in high-power builds Benefit: Power without the noise or drama.Who Needs This KitCTS-V owners adding pulley and tuneCars running ethanol blendsBuilds with ported blowersDrivers who want safe fuel margin If you plan more power next year, install the right pumps now.
