Guys, I need some help here.
I suspect my Mikuni fuel pump is spoilt.

Is it normal for the fuel to flow through from the inlet and out the outlet when the bike is not running?
I have tried to reconnect it the opposite way, and fuel flows through into the outlet tube and out the inlet tube!!!!

After rebuilding the Mikuni fuel pump using the repair kit with the brown plastic diaphams, I got the same result, petrol flows through as though it was a normal pipe.

Now if the pump is a goner, can this pump be used to replace the original fuel pump?
It's got 2 outlet tubes though and the flow is 65 Litres per hour.
Motorcyclists are the nicest people on the road, try not to kill us.
