A few more picture of the Cs
just a comment on the fuel filter that you shown in the CS setup
in my humble opinión metallic fuel filter cartridges had too high flow loses for an original mechanical fuel pump
it is advisable to use more simple fuel filters in this case and leave the metallic ones for the electric pump that you will find in your CSi
mechanical pump gives only between 0,21 to 0,25 bar pressure, ask me how i know this...
