RR'77 - I sourced an aftermarket fuel pump for my application, and found there are multiple sources for pumps that meet the required spec, which has more to do with high pressure capability rather than lph (gph) flow rates - the Duratec likes 4.2 bar, I believe. Provided CC can provide all the other items such as the hangar, the white polymer sleeve, sock filter, etc., a suitable pump itself is not difficult to obtain. At least not here in the U.S.A. And mine was < 100 bucks American, and shipped to me in a few days.
You might try a search locally for a suitable high pressure fuel pump, and if no luck, try TRE (cannot recall the specific part number) based in Fallbrook , California or Deatsch Werks DW200 from Oklahoma City, Oklahoma. I am sure there are others.
My S3 car w/ CSR260 2.3 Duratec came with the standard CC fuel pump, but a dyno session revealed it to be inadequate. I then had a DW200 which worked well, but an unfortunate coolant leak onto the MFRU fried that, and I replaced it with a TRE ($69 USD!!), which works equally well, which was proven on the dyno. Either of these pumps may require enlarging the white polymer sleeve by a couple of mm, but that is an easy lathe job, and once done, fully adequate and inexpensive fuel pumps are readily available, albeit from America.
