I have a 2003 Freelander TD4, so on Wednesday it blew the fuel pump fuse whilst driving, I have replaced the fuse, fuel pump and fuel filter and still it blows the same fuse :/ It'll drive for about 4 miles before blowing the fuse but it does without fail between 4 and 6 miles. Can anyone suggest anything else other than the fuel pump and filter because I thought that would fix it?

A trapped or damaged wire insulation would be my guess. You need to check the wiring from the relay to the pump.

That's what I was thinking too.
If you don't find a wiring fault, it would be useful to measure the current drawn by the pump. If there's a clog in the line it could be loading the pump down too much. Thankfully there's an access panel for the fuel sender in the tank under the back seats, so you can check the line all the way from the filter sock right up to the HP pump by the alternator.
Sorry for the late reply, There was a clog in the fuel line. I tried blowing from the fuel pump back to the tank, at first there was resistance then it suddenly cleared. The downside being that the clog is now floating around in the tank, the upside is it works! Thanks for your answers and ideas, at least it's working again. I'm gonna get the tank off and flushed very shortly

Quality result 
and a quality call by @guineafowl21 - give the man a medal
Would diesel additive break down the clot rather than having to strip out and drain the tank? Seeing how the tank cradles corrode, it might not go back on!
I have no idea about the additive, its just a thought!

I'm surprised that a piece of debris large enough to block the pipe, or stall the pump, managed to get through the pumps strainer gause.
At least it's working again, provided the clot doesn't return to cause more trouble.

I was amazed at my old car when I had to change the in tank pump on that in the end I drained all the diesel out and then hovered everything out as we have a hoover that does water ect..

Cheers!
Not sure about additives, but as Nodge says it's very surprising a clog managed to get into the line. Thankfully there's an access panel for the fuel sender under the back seats - I would be doing this as soon as possible since, if your strainer is damaged the problem may well come back. If (hopefully not) a piece of pump has broken off and clogged the line then you will have blown it back to the sender and it may be in the gauze bit.

I'd think it has a short somewhere.

Are you sure the clog hasn't come back? If you haven't removed the offending item it'll be rattling around waiting to cause problems again. It'd be odd if you happened to find a blockage and a chafed wire simultaneously.Ok now for an update, I ordered a filter and pump from the bay of E, fitted it and all was good except now it's popping the fuse again
I'd keep the eBay pump intalled till you've solved the problem, then think about swapping it for a decent one. Those cheapo ones have a habit of leaving you stranded.

Why not take out the sender first - you can inspect some of the tank then. Also, if the gauze is intact you can assume the clog is within the sender, and if not, putting a new gauze on should solve the problem.
I doubt flushing the tank will help much, unless there's a good reason like you've been filling the FL with old plastic drums of 'cherry juice'

Fair comment, just one question, what is 'cherry juice'??
