Dirty old ring piece

Poxy fuel pump was the issue, supposed to have 2.9bar on tickover and it was just under 2bar.

then as it comes on boost, or any form of load, instead of the fuel presure rising towards 3.7bar as it was supposed it, mine decided to drop away to about 1bar

new fuel pump fitted and happy days, boost capped at about 18psi for now, but will get the ring out the way and set it to where it can handle it a bit better, which should be 22/23psi

gives me tomorrow to get the MO's and Prada's on there, good old clean and Euro's etc, then pack up in the evening, Whoop Whoop
