Hi all, recently purchased my croma, it's the 2.2 petrol prestigio, and have discovered a petrol leak which apears to be from the right hand side of the high pressure fuel rail, it looks like the end will come off by undoing the two bolts and was hoping there might be an O ring or gasket in there, wondered if anyone had any info on this, any advice would be appreciated, hoping to post some pics very soon. thanks in anticipation of your help.
