G'day! I have done a search and have not found any info on these pumps and flow characteristics on a single overhead cam rb30. Has anyone else got one of these? What size should I be running in the front? 1.2mm? Should I block the rear one? Google is useless! I will also have a drain of -10 in the front of the rocker to the oil return in the block just In case anyway. Any help is greatly appreciated Cheers, Nick
