Hey mate just to let you know that I had a 3.9 and the pump failed. Was going to cost $400+ for a new one but instead I used a vl commodore pump which was worth $80. Worked great! Probably wont help you tho as you're looking for an inline one but it might be easier to find specs on a vl commodore pump rather than a disco. Hope this is helpful.

You want a Bosch 070 fuel pump (full part number 0 580 464 070) - generic replacement for a crapload of cars. Available on Ebay, or just go into a Bursons... Should be able to get a brand new genuine bosch one for $150 or under, depending on contacts.
Ideally you should run a surge tank/swirl pot to feed this pump, but my secondhand pump has been sucking straight out of the main tank for 4 years and I'm still wating for it to die
Some people have had them last only a few weeks without a surge tank though.

As long as its a high presure pump then its all good> On the injector rails there is a regulater to regulate (funny that ) the fuel flow.

Thats how I've setup my project (not running yet). Low pressure pump from fuel tank to swirl pot with a return line. High pressure 070 type pump from the Swirl pot to the 3.9 and then the return comes back to the swirl pot.

I just chucked a Disco tank and lines in, not hard and the wreckers dont want much for the tanks.

They don't regulate the flow so much as they regulate the pressure
Like Nottie says, pretty much in high pressure pump will suffice, as its the regulator that governs pressure
What tank are you useing, you'll be needing a lift pump and surge tank/swirl pot to make it work proper like
