fuel pump draining back to tank

One thing to keep in mind is that a lot of people talk about the fuel getting or running back to the tank.
The only fuel that runs back is what is in the lines, as it is not physically possible for the fuel in the carb bowls to run back.
Evaporation is what empties bowls.

On another note, I know a lot of people don't like the thought of running an electric pump.
The electric IS the way to have instant fuel in the carb and instant starts.
After the electric my car starts pretty much before you can get your hand off the key.

Here's a video to prove it.:D
This is first thing in the morning and the car had not been started since early the day before.
(Neighbors mower was running in the background)
