[Bretts AU]

Hi all, I'll be looking at replacing everything fuel system related in my 2000 AU fairmont 6cyl sedan live axle. I'd like to replace these items just to be on the safe side, plus I think its probably time as I don't know if they were done by previous owner.

Only thing is Im struggling to find the right parts I need:
Fuel pump
Fuel filter
Injectors
Fuel pressure regulator


All I'm finding for fuel pump is the whole module & pump for $200+ but I just want the pump.

Ive found a fuel filter on super cheap part number is Ryco Z528 is that correct?

Injectors, I don't know if its worthwhile to buy new or just get a 2nd hand set reconditioned.

Regulator, Ive read up on them saying they can clog up, again don't know whats better, new or clean a 2nd hand unit.

If anyone is able to help out with part numbers, pricing, where to go to buy parts please let me know.

I have SCA, Coventrys, Autobahn or Veales close by.

Also what is the benefit of rotating the pump sock? haven't found much extra info on that

Thanks all
(I've had a search as well on here, just don't know what to look for)
