I seem to remember someone saying that the busa has no fuel return?? can someone shed some light on this please as I would like to find a new fuel tank, how is a swirl pot used??? any help appreciated!

If I recall correctly the 'Busa fuel pump and regulator are one piece with the fuel flowing from tank through pump and regulator back to tank. The high pressure pipe then goes from regulator to fuel rail with no return. This set up is fine. I used an aftermarket fuel pump and separate regulator, going tank, filter, fuel pump in the rear and fuel pipe to regulator, return from regulator to tank and feed pipe from regulator to fuel rail.

This system works well but I have encountered some fuel surge when the tank is not full (fuel slops to one side on hi g turns and starves the pump) so I will probably modify the system so a low pressure pump feeds a swirl pot and the high pressure pump takes its feed from the swirl pot.

Thanks for that, what pump/regulator are you running?

Early Hayabusa's ran a fuel pump outside the tank and had a pressure regulator and return back to the tank. From 2002 onwards, this was changed to an in tank pump which has its own regulator. All the latest Suzuki bikes run this system and it works well. I have a GSX R1000K7 fuel pump mounted in the bottom of my tank with a small swirl pot built in to the tank. There is only one line to the fuel rail with NO return. This makes the installation very simple and extremely neat as there is no need for a return pipe or pressure regulator. See my archive photos of before and after to give you an idea of the changes and the clean lines under the bonnet.

Mine is a 2001, I will have to have a look and see what Malc supplied me with.

It doesn't matter what year your engine is as mine is a1999 and it converts easily to the later type fuel pump. All that you need to do if it is the early type is remove the fuel pump from the throttle bodies and purchase one of the later type pumps. fit it into your tank and run one pipe to the fuel rail. That's it.
