John,
Look at the size of the two holes in the hollow bolt that secures the banjo to the pump. Compare the area of those to the area of a -8 hose and I think you will see that the banjo is not a good choice. I would much prefer a "sweep" 90 i.e. that is a 90 degree fitting that uses a small length of radius bent tubing to make the 90 degrees. Remember if the pump starts to cavitate when you go to full throttle and motor goes lean the next thing to burn are the piston tops. Even though the pump is a fixed displacement pump and it is pumping gas into the injector system, the pressure regulator valve is returning the unused fuel to the tank and also all pumps leak internally, high pressure side to the low pressure side (the pump inlet) which at low flow demand can prevent the pump from cavitating but when the flow demand increases the amount of fuel circulating internally drops and the demand for additional fuel from the tank increases and at this time it may cavitate. One type of "patch" that is done is to connect the fuel regulator return line to the inlet line of the pump, which can provide enough flow make up to prevent cavitation. With this set up you may experience some heating of the fuel as it picks up heat from the pressure control valve. If you happen to consider this arrangement contact me as there are some specific plumbing configurations that should be used.
