VIS Motorsport 2.0 TSI/TFSI EA888 HPFP upgrade kit (also applies to EA855 and 4.0 TFSI V8)

[Sticky]

Upgrading the HPFP (high pressure fuel pump) is a critical part of modern Volkswagen and Audi tuning. This is especially true when wanting to run 100% E85 ethanol. VIS Motorsport's HPFP upgrade kit will help you increase pump flow.

Specs:

• 20% more surface area and is capable of over 150bar of pressure.
• Ready for big turbo applications or just for stock power giving another 10 bar fuel rail pressure and some extra hp.
• Piston head optimized for ideal fuel flow direction
• Piston surface hardened and heat treated in 2 different stages
• Laser marked for better traceability and protecting from fake replica
• It comes with fully detailed instructions including step by step fitting images.
• Each HPFP internal kit is sold as a rebuild kit only(not complete unit),but you send us your pump. We’ll inspect it, rebuild it, test it, and ship it back if you are not able to install! Either you can choose from our new complete units.

This HPFP applies to EA888, EA855, and 4.0 TFSI V8 motors. The V8 will obviously need two upgraded HPFP's.
