Hi Clois,
I'm going to violate my rule
and cover more than one subject below
First, here's my filter arrangement (I went with Aeromotive's recommendations):
100 micron filter -> pump -> 10 micron filter
This way, the 100 micron filter protects the pump from "tank trash" and the 10 micron filter protects the injectors/carbs. The pressure drop across a high-capacity 100 micron filter should be little enough not to lower the pump intake pressure too much.
Second, "fuel starvation in turns"
can be caused by at least two things: fuel sloshing away from the fuel tank pickup, or fuel sloshing away from the jets in the fuel bowls on the carb. As you would expect, the solutions to these are different depending on the hardware
On a carbureted engine, the fuel bowl problem is the most likely cause. An EFI'd engine would probably suffer from the fuel tank slosh problem.
This difference is because the fuel bowls in the carb(s) act as a reservoir, where the (usually) only reservoir in an EFI system is the tank itself.
If you have carbs and you experience this sloshing effect, there are adjustments and small mods you can make to the carbs to help minimize the effect. "Dog whistles", bowl vent extensions and float level adjustments come to mind.
Third and last, I put my pressure regulator on the firewall where it is away from the major engine heat and vibration. I've never liked the engine as a place to mount that item
Hope this helps,
Tom
