As David Vizard, an engineering authority on most things automotive, once had it, "Fuel supply is the lifeblood of performance-more power requires more fuel." In other words, any kind of performance upgrade-like larger injectors or forced induction-cannot realize full potential without a fuel pump that can meet the engine's increased fuel demands.
However, this should be in harmony with the fuel injectors and requirements of the engine. Excessive delivery on a pump will result in poor fuel economy or flooding of the fuel. Proper tuning is actually very necessary to keep everything in order and ensure that the full effect of the upgrade of a fuel pump is reaped.

Can Fuel Pump Replacement Increase Performance?
A new fuel pump would certainly help the vehicle perform better. This would definitely be so in the case when the present pump has worn out or is much smaller in size compared to the modified engine. The main purpose of any fuel pump, whether it is high-performance or used in regular cars, is to deliver the correct amount of fuel at the right pressure. The fuel pump of a normal car runs around 40 to 60 PSI. In high-performance cars, though, pumps able to produce 100 PSI and upwards are needed since the fuel demand is going up. A high-flow fuel pump-just an example, like Walbro 450 LPH-offers high flow characteristics and will handle the fuel delivery much better in over-600 hp applications.
In most upgraded applications or those where forced induction systems are fitted, the stock fuel pump cannot support enough pressure under load. A weak pump means the fuel-starved engine will rapidly lose power and can even suffer from misfires or detonation. Replacing the fuel pump with a higher horsepower-rated one will ensure the proper amount of fuel flow to the engine, vastly improving throttle response, acceleration, and overall engine performance.
As a specific example, most performance enthusiasts who upgrade to turbocharged or supercharged systems in support of high-flow pumps often install them. In fact, a case study on the 2018 Mustang GT installed with a supercharger demonstrated how the upgrade in fuel pump design allowed the engine to safely achieve 700 horsepower, nearly 30% over stock fuel system horsepower. The new pump provides consistent fuel delivery, even under extreme load, preventing any lean conditions that might be dangerous.
