Show original supplier description
The CTS Turbo Stage 3 Fuel Pump Kit is an integrated fueling solution featuring a high-output Walbro 450 LPH E85-compatible in-tank fuel pump. This kit is engineered to fortify the low-pressure fuel system, addressing a common limitation in performance upgrades for EA888.3 engines. Included in the kit are genuine Walbro components such as the fuel pump and filter sock, alongside custom-machined CTS parts including a black hard-anodized pump adapter, fuel pump spacers, and a venturi stand-off. Viton O-rings, nylon wire crimps, a 7.5mm drill bit, and stainless steel fasteners are also provided for installation. The kit is designed to support vehicles with the EA888.3 engine, specifically targeting MQB platform models. Fitment includes a wide range of Audi A3 (8V), A4 (B9/B9.5), A5 (B9/B9.5), and S3 (8V) models, as well as VW Golf/GTI (Mk7/Mk7.5) and Golf R (Mk7/Mk7.5) models. The Walbro 450 LPH pump is capable of supporting in excess of 600 horsepower, making it suitable for high-performance applications. Installation requires specific tools, including a 7.5mm drill bit provided in the kit. An installation guide is available for download. The product comes with a warranty disclaimer stating that Walbro fuel pumps are tested to operate correctly and no additional warranty is provided on the fuel pump itself.
