The correct Bosch part number is 0 580 254 044
Available at Truechoice for $300:
http://www.truechoice.com/menu.asp (search using Bosch as vendor name)
You can find it elsewhere as well now that you have the part number.

Here are the figures from Bosch. You can find these from Bosch's German website as well: http://www.bosch.com.au/sat/motorspo.../fuelpumps.pdf
I'd recommend two 979 pumps (used on the 70s and 80s CIS injected Porsche 930s). Though they flow slighly lower, you can find these for $179 each.

I recall reading that tests have shown the 044 is good for 230, much like the 979 has proven effective to 200.

Does anyone know anything about this pump? I'm looking for an external pump capable of 500 hp. Is this one internal or external?
TIA

The largest capacity generic Bosch electric fuel pump is 0 580 254 984 (also
known as GFP 216). It can be used either as an "external-to-tank" pump, or
as an "internal-to-tank" pump. The inlet is approximately .5" diameter, and
is shaped as a slip-over hose nipple. The outlet is a 12mm female thread,
and houses an integral check valve. Most hydraulic shops carry adapters
which will screw into the outlet, and adapt the 12mm/copper washer seal to
something like a 6AN or 8AN hose fitting seal. At 12 volts, the pump flows
57 GPH(US) at 10 psig and 6 amps, falling to 37 GPH(US) at 100psig and 13
amps. In between these two points the curve is almost a straight line.
There are other part numbers which share the same rollervane "pumping cell",
and will flow similar capacities, but they introduce idiosyncrasies
associated with their OE hookups and packaging requirements.

"Part number 0 580 254 023 is one such offshoot, that has an integral "open filter bottom". This in-tank pump can double as a pump/filter combo unit. However, the filter screen area is small (flat screen 60mm diameter, by 70microns fine), and CAN plug prematurely unless you either place a filter screen in the vehicle's fuel filler neck, or maintain a very clean fuel system."
That e-mail is not entirely correct. The 984 pump is the one that everyone seems to use for flow comparisons. Flows the same as the 979 pump. Also in the Bosch link I provided.
It may help to have the Porsch part numbers for cross-reference:
The 979 pump is Bosch PN 0 580 254 979. This is the FRONT/primary pump (front since the gas tank is...uhh...up front) for 1980 to 1983 911 Turbos (as well as 928 S and 924 Turbo). BTW, may discount parts places will list their own part number for Bosch pumps. The Porsche part number is 930.608.111.00.
The 984 pump is Bosch PN 0 580 254 984. This pump is the primary pump on 1978 through 1979 911 Turbos and others using K-Jetronic (CIS) injection. Porsche part number is 911.608.102.00.
The 044 pump is Bosch PN 0 580 254 044. This is a competition pump used on 993 Supercup cars and others. Porsche part number is 993.620.104.80.

im usein 2 bosch 910's, they flow the same as the 984's etc but have a 5/8 inlet and m12x1.5 thread out, with 2 of these pumps you have more than enough fuel for 600+rwhp, they are half the price of the others at $250au

044's are a motorsport item, they can run at huge pressures while still retain high flow and moderate current draw.
Again, you can skimp on parts or get the best, there is nothing better than the 044's for the money. Pay a bit more but you will have pump capacity (with 2 x 044's) to look after 900rwhp ! (on a rotary !!!)

rice i sort of agree, but for the price of one 044 you can get 2x911 that flow more fuel than 1x044,
the 910 are rated at 3.6L per min at 65psi and the 044 is rated at 4.1 at 65psi,
i would rather spend less money and have more fuel flow!
2x910 are good for over well over 600rwhp and 3 of them are good for 1000+ and still cheaper than 2x044
i made over 400rwhp with one 910!

Yeah 10sec, I kinda agree too 
All depends how much you can get 044's for I suppose
The one big benifit of the 044's is the high pressure ranges (that are usable) depending on you or your tuners philosopy you can utilize higher than normal pressures, there by getting better atomisation and injector patterns = more efficiency.

i cant get them cheap real cheap but they are still twice the price of the 910's!
high pressure is all good, but as you get up to 75+psi some injectors can have troubles opening, and may even stay shut all together,
i have had the 910's up to 70psi static and they still work fine!!

Yeah I run my old ND Injectors @ 72 psi static with another 25 psi boost on top of that and never ever found a problem. (both on dyno and individual injector solenoid signal logs).
Knowing Bosch there are likley to be parts differences in the pumps which would make the motorsport items more durable, they are definatley more designed to be used at higher pressures as no other Bosch pump is recommended (by them or their trained technicians) anyway
The cost differences are minor in my view, specially compared to how much the average enthusiast spends on their car in total.
