Show original supplier description
The Racetronix DIYDPK-C56 is a comprehensive dual fuel pump kit engineered for 2003.5-2013 C5 and C6 Corvettes, designed to support significant horsepower upgrades ranging from 600 to 1400HP. This kit features twin Racetronix turbine fuel pumps, available in 255LPH or 340LPH configurations, known for their reduced noise and enhanced reliability, even with E-85 fuels. It includes a robust stainless steel pump bracket and a billet dual pump coupler with Viton o-rings for a secure seal. The package also contains a high-pressure, non-kinking fuel tube and a Teflon 10-gauge PnP dual in-tank harness, which is E85 compatible. Included in the kit are an intermediate PnP harness and a dual PnP power harness, both utilizing 10-gauge wire for optimal performance and reliability, ensuring minimal voltage loss to the pumps. The system is fully weatherproof and plug-and-play. The DIYDPK-C56 is specifically designed for C5 Corvettes manufactured 2003 1/2 and later (VIN # 114931 and up) and all C6 Corvettes through 2013, excluding the ZR1 model. Due to the complexity of fuel system requirements for high-HP applications, Racetronix advises customers to verify their module number by emailing their VIN before ordering, as returns on open box pumps are not permitted. For applications exceeding 1000HP, upgrading to -8 Teflon hose and potentially welding -8 fittings to factory LS2/LS3 rails is recommended for improved fuel distribution. It is also noted that this kit does not maintain the jet-pump/venturi functionality of the factory fuel pump module.
