If using a external pump, just use the std xr4i/cossie pump the 941, about £70, will supply well over 350 bhp, also depending on what rail you are using, if you use top feed injectors, instead of side feed zetec ones you could pick up a set of std yellow injectors for around £40.
Any injection tank will be fine, external pump one.
The 941 bosch pump has the common post connector, that the plug goes onto/over, the uprated 044 pump(not needed for you) has screw terminals, so most put on a ring terminal on there.
