I'm starting to plan my fuel system in more detail. I had planned to use a pair of cossie fuel pumps as they are familiar to me and reliable, however I am considering using in tank pumps and have noticed uprated Jap ones on Ebay that go to 500bhp and I quite like the idea of quieter in tank pumps.
I'm scratch building the car so the tanks etc are all to be fabricated so I'm really wondering what the real word ideal fuel system would be..... i.e. low pressure in tank pumps feeding a swirl pot in the engine bay and then high pressure pumps etc? or will a simple pair of high pressure in tank pumps be just as good?

Cheers for the response.
I'm going to be running twin turbos on a BMW V12 and power will exceed 500bhp. In the original car each bank is run separatelly with its own ecu, pump fuel rail etc.
This is why I was planning on keeping the separate fuel rails and running two cossie pumps which would be good for 750bhp.
I will be baffling the fuel tank carefully so in therory (if done correctly) there will be no need for a separate swirl pot.
The car will see track action and should handle very well so surge will be an issue I need to address.
