You'll be fine with a mechanical. It's not a high output right? It's when you get into electric high flow that you see flooding at idle.
I run (2) 110gpm pumps right out of the tank and (Y) in to a single line to my regulator then carbs. Set at 7psi. If you've been driving for years and you don't flood or go through spark plugs like mad, I wouldn't worry.
What part of so cal are you in? Pictures like San Bernardino but it could be east San Diego for all I know.
