under the seat.
Behind the backseat.
It is in a black plastic box just below the battery.
If its like my '03 1800 VTX, then the fuel pump and filter are inside the gas tank. Take the tank off by removing the rear bolt, lifting the rear of tank, disconnecting the supply line , vent line and recirc lines. Disconnect the wire at the connector. Lift off tank. Pour out the fuel, rest it on something soft, unbolt the inner side plate and sorta wiggle the fuel pump and filter assembly out. Pain in the ass.
the starter relay is located in the fuse box under the hood behind the battery. i believe its the biggest relay from the rest of them.

Disconnect the cable ends from the battery. Loosen and take off the hold down bracket. Take the cover off of the battery if it has one. Lift the battery out of the car. Installation is the reverse of these steps.
