CTS Turbo Stage 3 Fuel Pump Upgrade Kit for VW/Audi MQB Models (EA888.3)

We are proud to release the new our CTS Turbo Stage 3 Fuel Pump Kit for MQB GTI, MK7 Golf R.  As you may already know the TFSI fueling system has two separate fuel pumps, the LPFP (Low-Pressure Fuel Pump) and HPFP (High-Pressure Fuel Pump).  While there are a number of options for HPFP available, including the Autotech HPFP, there are limited options for fortifying the low-pressure fuel system.  CTS has developed a fully integrated fueling system, which utilizes a Walbro 450LPH E85 compatible in-tank fuel pump that is capable of supporting in excess of 500HP.  If you're looking for a fuel pump system to support all the power that your engine can handle look no further than the CTS Turbo Stage 3 Fuel Pump Kit for MQB GTI, Golf R, 8V Audi A3/S3. NB: please keep in mind that some modifications to your fuel pump basket is required. Some baskets differ from each other so installation should be performed by an experienced technician. Torqbyte Controller is an optional add-on and strongly recommended. Software tuning is required.
