If you are changing the pump I would change the filter at the same time. Below is details of how to do this as well as change the pump.
Prepare yourself for a lot of hassle and swearing. Jack up the rear of car, remove the rear wheel. Just to the bottom right of the wheel arch is where you'll find the fuel filter and pump, behind a snow shield. There are two rivet plugs holding this in place, remove the two center plugs from these riv plugs. I found it easier to tie a rope through the hole and then I tied it around the front and rear window aperture to keep the snow flap out of the way.
Underneath you will see two 10mm bolts undo these and the cradle should be free. Remove the electrical plug from the pump, and also the little earth plug from the side of the filter, them remove the fuel line from the top of the filter then remove the fuel line from the tank which goes to the pump. (both these should have a plug type connector with two blue push-in release tabs)
Once the cradle, fuel line plugs, and electrical and earth plugs, have been removed place the cradle on a bench. This is normally where the problem starts.
You will probably find that the filter is seized in it's plastic holder at this point. Remove the pump from it's holder and place somewhere safe. Now what I had to do with mine was drill a hole in the bottom of the plastic cradle right opposite the bottom of the filter big enough to get a long 3/8 drive shaft in, I then placed a long reach 14mm socked on the end of the drive shaft then hit with a hammer seven sorts of Shiite out of the end of the drive shaft.
After about ten minutes I Finlay got it out. Before you put the new one in plaster it in anti seize copper ease grease. Check the the little earth connection has not rotted away if it has make a new one out of a small bit of alloy.
Before you put it all back together drain the sedimenter container, this is a black container near to where the filter and pump are situated. This has a little tap on the bottom for drainage.
Once you have put it all back together turn the ignition key on but don't
start the engine, you will hear the pump working this will go for about 20 seconds. When it stops do the same again after 20 seconds you should be able to start the engine. (The freelander has a self priming fuel system)
check for any leaks near the fuel plugs, if all is ok fill around the little hole you drilled with silicon mastic then replace the snow shield, put the wheel back on and lower to the ground.
Job done.
