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.

Frequently Asked Questions (FAQs)

1. Will this fit all 09–15 CTS-V models?

Yes. This kit is designed specifically for the 2009–2015 Cadillac CTS-V platform. The pumps and install components match the factory fuel module, so the fit is direct without major modification.

2. Do I need a new fuel controller?

In most cases, the factory fuel control system works well with this kit. Only extreme power builds with large injectors or custom tuning may require an upgraded controller.

3. Can these pumps handle E85 fuel?

Yes. The DW300c pumps are compatible with ethanol blends, including E85. The internal materials are designed to resist ethanol-related wear and maintain stable flow.

4. Are two pumps better than one large pump?

Dual pumps divide the workload, which helps them run cooler and last longer. This setup also provides more stable fuel pressure during high boost or hard acceleration.

5. Is the kit noisy during daily driving?

No. The DW300c pumps use a turbine design that keeps operation quiet and smooth, similar to stock behavior in normal street use.

6. What power level can this kit support?

The dual 340 LPH pumps provide enough fuel for high-output street and track builds when paired with proper injectors and tuning. Exact limits depend on fuel type and engine setup.

7. Does the kit include wiring and hardware?

Yes. The package includes the required wiring, connectors, filters, and mounting hardware needed for a complete and safe installation. The DeatschWerks 09-15 Cadillac CTS-V DW300c Fuel Pumps solve the biggest weak point in modified CTS-Vs. They deliver real flow, a clean fit, and dependable daily use. If you want power you can trust on every pull, this kit is the smart upgrade.
