Mat,
As a founder member of the "Bosch burnt out fuel pump club", I killed two, I came to the conclusion that modern FI pumps arent made for sucking but they are excellent at pushing.
Hence I now fit a swirl pot into the fuel tank with the return line feeding right into it, stick a standard lexus ls 400 in tank fuel pump set at a permanent 12 volts into the swirl pot and it all works really well.
No fuel starvation when giving the car the beans or when cornering aggressively and fuel pumps last forever. Plus its really quiet in operation.
Cheers,
Tony
