Carb fuel “log” vs dual fed lines?

Guess I'm stuck in the past. (Regulator? What's that?)
Same here.
and I also have an airgap style intake , and fresh air. But
my 3/8ths fuel line is all hard from pump to carb, minus a lil jumper to the dual-feed. The filter is at the back.
IMO,
Mechanical pumps, on the street, are more or less self-regulating, I said more or less. and non of my Holley-carbs are sensitive to over-pressure from my pump.
Yes, I guess it is possible, that I'm just lucky.
BTW,
my large-capacity, metal canister, EFI fuel filter was new in 1999. over 125,000 miles ago. So I guess I'm lucky with that as well. I mounted it in front of the Passenger side front spring mount, with hard lines of course.
