Stock fuel pump limits

I ran the carter HV pump for many year, had many times of starvation, but in the end. It was never the pumps fault.
Fixed cracked rubber vent hose(metal line plugged full of bugs)
Installed headers, clip cam off of fuel line next to header. Fuel line to close to header (vaper lock)
insulated fuel line in that area.
built a shield to block radiator heat from fuel pump (made it worries)
added a little electric fan to blow on fuel pump it self.
added insulated spacers on carb.
even tried the wooden clothes pins on the fuel line.

some of these things help but none of them fix my problem. The fix?
A cheap autozone inline fuel pump(yeah that little cheesy on with the look like a filter with two wire on it)
As long as i turned it on, i never ran out of fuel in the 1/4 mile on a hot summer day.

I think that carter mechanical fuel pump will supply all the fuel that most will need. As long as you can keep it away from the hot spots.
That's why a electric pump works so well, they don't boil the fuel, the push it thru.
A return fuel line would have fix all my problem as well.:BangHead:
