Be Prepared
After I got about 8 miles from home, I started smelling gasoline, in my '79 F-250. Raised the hood and it wasn't hard to find. If you've installed an inline fuel pressure regulator, as I did, when adding an electric pump for a booster, keep an eye on your Purolator,
(Pro-Fuel Regulator.) There is a necessary bleeder hole on the reg. If and when the diaphram ruptures, you will have a 1/8" hole spraying gas on your engine. If I ever buy another one, I'll carry a self tapping, sheetmetal screw to plug that hole. I had spare fuel line that I removed from my spare fuel tank, so I removed the regulator, to drive it home.

Pressure regulator
I don't think you actually need the reg, but I've seen big V-8's that have had a flooding problem and the reg was the best cure unless you want to tear into the carb and replace the float valve. I'm actually running 2 pumps so I like to play safe.

Putting a screw in that hole probably blocks the vent for the diaphragm. That will destroy the regulator. Of course with the diaphragm blown it is shot anyway, but I would hate to have someone block the vent in a good regulator.
I like to run a hot fuel return line which also limits the amount of pressure in the fuel line. But like FSC says the pump will only put so much pressure on the line even if dead headed.
If I remember right the Ford hot fuel return system uses a .040" or .060" orifice in the system.
