Right, i am a tad lost with this, my cars soon to be running 520 bhp, and i keep reading mixed things after hours of searching.

Some say a single 044 is fine, others seem to say 2 x 044's, then there's lift pumps into swirl pot into twin 044's......
What do i genuinely need, car isn't going to be doing any track work to be honest.......

If it's just for the road with no track use then single 044 will suffice, and -6 line to a single fuel rail. A new OE fuel filter is a wise choice as well. If doing some RWYB's then make sure there is plenty of fuel in the tank too.

Something people forget is to make sure there is a constant voltage of between 13.5v - 14.5v to the pump under all loads, the less volts to the pump the less fuel is pumped out which is not a good thing at that level of power, so if you haven't replaced the wiring to the fuel pump then do that too.

Thats excellent, rep'd

It has brand new wiring on it, uprated loom thingy, and i have a voltage gauge wired directly into the fuel pump terminal, which is right in my line of vision, so thats all taken care of.

Just a -6 line needed then

Yes I had a fuel pump rewire , cw looms do a loom if I remember rightly .
