as topic states converting to AN fittings need to know what thread pitch and size the s4 fuel rails use. Any help is greatly appreciated.

Thanks https://www.nopistons.com/forums/pub...#>/biggrin.gif

theres 2 different ones, the damper and regulator are one pitch and the banjo's are another.

12mm × 1.25 adapter is the side with the fpr and pd.



and



14mm × 1.50 adapter for the banjo fiitting sides



for the TII S4 fuel rails.
