The CTS Turbo Stage 3 fuel pump kit is designed for MQB GTI and Golf R vehicles, as well as Audi A3/S3 models with the EA888.3 engine. The TFSI system uses two separate fuel pumps: a low-pressure fuel pump (LPFP) and a high-pressure fuel pump (HPFP). While several HPFP upgrades are available, there are fewer options for improving the low-pressure system. CTS Turbo has therefore developed a fully integrated system with an internal Walbro 450 LPH pump, compatible with E85 fuel, which supports more than 500 hp.
Important: installation requires modification of the fuel pump basket. As the baskets differ between individual versions, installation should be carried out by an experienced technician.
The Torqbyte controller is available as an optional extra and is highly recommended. Engine software tuning is also required.
