It is the fuel pump mounted in the bottom of the tank.

The info needed is flowrate , working pressure and relief valve pressure.

I don't even think Honda has that published anywhere...Time to order one and test for yourself ! Since they are all Keihin designs, I'd guess all the 450/250 FI systems are running very similar fuel pressures.

Does anybody know the Keihin model number for the pump. Then I can contact Keihin direct. Thanks and Happy New Year.

Perhaps you can just call Keihin and ask them what the PN is... I bet they'll be able to help you out if you tell them what the bike is... Sudco might be able to help, as well.

Here is what I found.

Fuel Pressure- 333-353kPa (3.4-3.6 kgf/cm2, 48-51 psi)

Fuel Pump Flow- 50cm3 (1.7 US oz, 1.8 Imp oz) minimum/10 seconds

Hope this helps

Matt
