RH...The big Aeromotive A1000 pump isn't that great a pump. Yes, it outflows the Bosch 044 at low pressures, but above 50 psig, the Bosch 044 actually outflows it, pretty substantially. When sizing pumps, you always have to look at the overall flow at the fuel pressure you want to run. I wanted to go A1000, but it just didn't add up given the pressure I wanted to run. The nice part is one could size a really big injector and then turn fuel pressures down to get proper atomization to really take advantage of the flow characteristics of a given pump. So many variables...
