The Official Bahrain Grand Prix Thread

The interview was in German. I believe the word vacuum is a slight translation error. Venturi lift pumps work much like a vacuum and when they malfunction they suck air instead of fuel. Vapor lock caused by the lift pump. 

I agree, but we know the chances of that happening are zip. 

I saw a post post-race, no idea where now, that said the fuel was sloshing too much and wouldn't stay in the pick-up area due to the g-forces the cars are experiencing and that was what caused the cars to stop. We all know they figure that stuff as closely as possible to have 'just enough' at the end of the race so maybe a simple internal fuel tank rework or something else entirely.
