When installing a new fuel tank, it is necessary to disassemble the accessories from the old tank and to install them on the new tank.
The first step is to remove the old tank from the bike.
Place Bike on Centerstand.
Remove Seat.
Remove Left Side Cover. This shows the right but the left is the same.

Lay old tank next to new tank. At this point the old tank still has fuel in it and must be drained into an approved container. 5/16" Inside Diameter fuel hose works fine for the transfer. Attach fuel hose, point other end into a container and turn petcock valve to ON.

When no more fuel flows shake the tank side to side and get as much to flow out as possible. You won't get it all. Then turn petcock to OFF and detach the fuel hose. Securely close the fuel container and store in a safe location. Next, turn the old and new tanks upside down.

Transfer Float and Sending Unit. When installed, turn the tank over and make sure the float is not stuck and moves up and drops back down freely. A long hooked probe to gently lift the float arm and a flashlight to see in the tank helps. Don't drop anything in the tank. If the float is stuck remove the float assembly and reinstall correctly.

Transfer front hold-down bracket.

Before turning the tank right side up again, go to a large sink or outside over some dirt or grass. As you turn the tank over more gasoline will drip out. Rock the tank around and get as much to come out as you can. Be careful, no open flames!
Next, transfer the rear hinge with the tanks right side up.

Lastly, transfer the fuel filler cap assembly. Do NOT drop any screws into the tank.
