So back to the questions that actually matter.

How much fuel flow do you need ? And it's an external pump you want ?

If it's sub 500hp, even a Walbro GSL392 would do. It's the external version of the in-tank pump.

If it's sub 400hp there will be are a few Bosch pumps that would do that are much cheaper than an 044, or the above Walbro.
