If the fuel pump is healthy then a std 941 pump is fine at your power level, if needing to buy new though may as well put on a 044 pump.
If you're new to cossies, you need to do a few things first, if not already done, they are absolutely vital, a fan rewire and a fuel pump rewire, nice and easy nice and cheap.
The after making sure it is serviced etc correctly, change belt/tensioner if age/mileage unknown, then get a fuelling check done, can save a melted engine for a very small outlay, compared to a engine rebuild.
