i have a mx83 with twin walbro intank pumps(which flow about 50hp each less than an 044), just has a regular 8mm t-piece intank with hose clamps running through the standard 8mm fuel line. made 520rwhp(auto) and have still have plently of fuel flow.
fuel pumps cost me $140 each and looks neat cause its all intank. im hoping to make it to around 600rwhp before the t-piece and single 8mm fuel line starts to restrict flow.
so in yourcase -8 would be big enough for probably 4x044 pumps without restricting flow so you will be fine, no matter how you join the pumps your not going to run out of fuel at that power level
