Right after the quest (which we unfortunately still don't know the answer too) to find out the flow on the bosch ...053 and ...909 fuel pumps, just a thought, what do the cossie boys use? they have external ones on the sapph (don't about 3dr's, escort cossies have internal ones) and quite a few of them run over say 350bhp - 500bhp for your average high powered road going one. It's a bosch pump but I can't find any info on it. Al I know is that Graham Goode does the uprated one which flows 200ltr per hour. Must be pretty good as the fuel pressure (depending on many variables) can be as much as 5.3bar on full boost.
