How to keep fuel up to the curb after shut off.

Some carbs you can pour a little gas down the vent tubes to fill the bowls. If it has sat for a few days fill it up and then start the car.

I normally don't keep a 60cc syringe of gas in the glove box.:D

The adding of an electric fuel pump is a good idea IMO.
Deleating the mechanical pump is your choice.
