Dunno if it helps or not but I got a voltmeter connected to the pump to warn me if voltage drops.

Also got a fuelpressure gauge but its useless on a turbo car with a rising fuel pressure. Ive suggested to SPA to make a fuel pressure/boost gauge that work on a turbo car, ie the low fuel pressure warning level rises and drops with the boost pressure.

standard warning level + current boost = new warning level

3,3 bar + 1,0 bar boost = 4,3 bar low pressure warning at 1,0bar of boost.
