Hello, my name is Mark and I will try help you with this.
This fuel pump is located in the fuel tank.
You can get to it by removing the lower part of the rear seat.
There should be large plastic cover. Remove this and you will see the pump and level sensor wiring and the fuel hoses.
For safety, you should disconnect the battery and also wait about 30 mins after switching the engine off before disconnect the fuel hoses and wiring plugs.
The lock ring can be difficult to remove without the special tool but a large pair of waterpump grips can be used carefully.
Make sure to note which hose goes where when you disconnect them.
Did you manage it ok?
