I have a 5 gallon fuel cell that came with -8 AN fittings in it. At what point does it become necessary to run a -10 AN?

Probally around 1000 hp total using power adders or on straight motor, but I don't really know as all of my junk makes less than that and I use a single # 10 to my 300 GPH pump, which is suppose to be good to 900 hp two number eights with the right system should be good to 1000HP + I would think, maybe not Try calling a couple of the companys that make good fuel system parts and ask them
