Hello,
Can someone guide me on this please?
1) How do I remove the fuel sending unit from the tank? Does it unthread with a pin-wrench, or spanner wrench?
2) Do I have to drain the fuel tank to replace to replace the sending unit?

The sending unit is underneath the car, approximately below the floorboard behind the drivers seat. It is installed below the tank rather than on top of it. This is a bit of a concern to me, as I have replaced many seding units on other cars from the top.

Please help.
