Radical mods take extreme amounts of fuel to make street-ripping power. If you bolted on a monster fuel pump to feed your street beast, you also need a fuel pressure regulator to control it. Some pumps crank out up to 12 PSI which will turn most carbs into the fountain at the Bellagio hotel in Vegas. By bolting on Edelbrock Fuel Pressure Regulators – Carbureted Engines, you have to power to dial in the ideal fuel pressure your ride needs to win. 1-year warranty.
