Rob my comment really wasn't aimed at you mate, it was aimed at the "older" generation who like to put everyone else down and prevent good tech discussions ever taking place.




It is certainly an interesting subject and topic, fuel systems are very hard to get 100% fail safe, anything that can help towards this is only a plus really,


ive never taken an 044 pump apart, but when they have issues its normally a flow issue under high fuel demand and the rail pressure drops at high rpm, nasty really as you have no idea your about to have a melt down because the pump is still flowing plenty to run fine low down. Its only when you ask them to raise pressure they fail.
This is similar to if one pump fails on a twin pump system and you are relying on the supply from 2 pumps to meet demand,


Its also fine having gauges and dials everywhere monitoring all this but when your "on it" in the car you just don't have time to look at them all and take in all the information, so it really does have to be controlled by the ecu or something that can take action for you.
And then the issue of what action you take, cutting fuel all together in something like a track car on a busy track circuit could be pretty dangerous, getting rear ended at high speed wouldn't be much fun,
I would be trying to get a low fuel pressure warning or pump failure to cut boost so you still have the ability to move under your own steam to get out of the way of others. That's something people who drive in a straight line on their own don't think about.
