Left Foot Gas Pedal. The (LFA) was designed for the driver that has lost control of only his right foot, with an (LFA) accelerator installed to the left of the brake pedal the problem of applying the gas is no longer a problem.
With the engine stopped, depress the brake pedal normally, several times. The brake pedal must be depressed before the engine is started in order to remove vacuum from the booster. With the brake pedal depressed start the engine. When the engine is started, vacuum is created and operates the booster.
