04 XB12R has become very difficult to start, I've had to crank it several times for 5 seconds each to start. I have no fuel pressure gauge but I disconnected the fuel line at the throttle body. I then put the supply line in a small plastic bottle and turned the ignition on to prime the system. The pump ran for a couple seconds and fuel basically dribbled out. Again I have no gauge yet but a very small amount of fuel with little apparent pressure. I hooked the line back up and tried to start it, same as always crank and no start. I dribbled a little gas directly in the intake and it fired/started instantly. I'm 98% that it must be a pump or internal line problem but just asking for a second opinion. Thanks
