Keihin Pump Connections??? (BMW 700 - A Car)

[raybrandes]

I am looking for help with the connections for a Keihin pump as used on the Honda TRX series.
From what I can gather, #1 goes to the injectors, #2 is the fuel from the tank and #3 is the return to the tank.
Additionally, I cannot find the polarity for the electric connection.
Can anyone tell me which is positive and negative, A or B?

A=-
B=+
1= high pressure to injectors
2= fuel in from tank
3= return to tank
I am not positive but I think that pump needs to be gravity fed.
I don't think it will work if the tank is lower than the pump.

Thanks for the data OldGuy! I will be feeding it with a low pressure pump.
