Saw a thread where a guy was having a few issues with HPFP. Thought it may be interested for those who have just had INTERNALS (e.g. not APR full pump installed). Link to thread here: LINKY
Has anyone else on here fitted the RS4 fuel rail on their S3 8P?
Also, does anyone know where the OEM fuel filter is located?
Thinking of doing this mod when I get back from Germany in a few weeks time. Need to get up to Revo when I get back so they can set up the map to accommodate.
Thanks in advance
