+===== Fuel pump connector polarity =====
+After disassembling the carburetors you may want to force the fuel to fill them again. Using the start button and letting the entire engine rawwing for a long time may be an high load for the battery, so you may prefer to provide 12 V directly to the pump connector.
+In this photo you see the polarity (red is positive and black is negative) of the connector from the wiring harness to the pump:

+You will hear the noise from the working pump. Ance the carburetors are full, the pump will stop.
