FWIW
I run a mechanical pump and factory style vapor separator with a return line. I have driven my cars all over the country in very extreme conditions and with all different kinds of gas. My car's fuel system is quiet, stock and dead reliable and would be easy to get parts for anywhere.
I don't need all that fancy racing stuff on my street car. How many of you can say you've driven your car at near wide open throttle for miles at a time, like over 5 miles at a time in 95 degree weather at 6000 feet alitutde? It never ran out of gas. I also drove it in 115 degree temps in Vegas last summer with the AC running the whole time.

I don't need no stinking vapor locking electric fuel pump on my street driven muscle car.

My carbs is bolted right to the intake manifold with no spacer/bandaid.
