Got the washers finished and tested - All ok and the spray pattern as fitted is good. Ran out of clips so some piping wirelocked in place until I can get more.
As you can see below fitted tie clamp clips to hold pipework in place.
Still need to tidy loom wiring and P-clip into standoffs in the bonnet but you can see the general idea......
