Update...
I found a slight kink in the 3/8" fuel hose between the electric fuel pump and the canister filter. I'm removing the filter between the tank and pump all together and replacing the fuel line as well as rerouting it to provide more of a straight shot.
I'm adding a 40 micron filter just before the fuel regulator to provide filtering. The one I purchased seems ok but is only rated for 300hp. I suspect I'm closer to 375. That being the case, it's only street driven so is it safe to assume that the fuel in the bowl would buffer any starvation issues?

Once finished it'll be tank-fuel pump-40 micron filter-regulator-carb.
Sound ok?
Many thanks to all who have responded!
