CTS MK4 Inline fuel pump kit

The CTS Turbo MK4 Inline Fuel Pump Kit provides a practical solution for VW MK4 platform owners requiring increased fuel flow to support modified or tuned engines. This inline configuration installs between the factory tank pump and fuel rail, supplementing the OEM system rather than requiring complete in-tank pump replacement. Engineered specifically for 1999-2006 Golf, GTI and Jetta GLI MK4 models, the kit delivers enhanced fuel delivery capacity needed for performance upgrades whilst maintaining reliability. An ideal upgrade path for turbocharged applications or vehicles running upgraded ECU calibrations demanding consistent fuel pressure under load.
