Prior tank removal:
* while idling, disconnect 4 pin black fuel pump connector and let the engine die, crank 1-2 times, ignition OFF. This will remove fuel pressure from the fuel line
* M8 bolt out
* lift the gas tank up and disconnect its rubber breather hose, very sure it will be stuck, so spry WD40 or similar and crack it loose by twisting, then disconnect it
* insert 2x4 between your tank and frame to gain more room while disconnecting the fuel line

* after reassembling and reconnecting everything back, turn ignition ON/OFF a couple of times to prime the fuel system, then fire her up at the first shot. While idling, observe any fuel leaks.
