I was reading Motorsport this month and they had an article about the attempt to achieve 1000 mph in a "car". To do this they will use a couple of jolly big jets/rockets attached to a very stream lined chassis/body shell. It will consume 1500kg of fuel in 80 seconds! Now to allow this to happen they need a rather big and powerful fuel pump. They decided to use an 800bhp V12 engine just to pump the fuel. Now that is a serious fuel pump!
