What You'll Learn
Fuel line size and pressure drop
The primary source of pressure loss in fuel lines is friction. As fluids travel through pipes and hoses, they experience friction, which reduces the pressure at which the fluid is delivered. Two factors influence the amount of friction in a fuel line: length and flow rate. Longer fuel lines result in more friction, and as the flow rate increases, so does the friction. Therefore, every fuel line will experience some pressure loss depending on its length and the fuel flow rate.
The pressure drop in the fuel line will impact the performance of the fuel system. For example, a pressure drop of just two PSI in a fuel line can significantly reduce the available flow rate, affecting the overall performance of the system.
When selecting a fuel line size, it is essential to consider the application, whether it is carbureted or EFI. Carbureted systems are more sensitive to fuel line size, while EFI systems may require different considerations.
In summary, to ensure proper function and performance of a fuel delivery system, careful attention must be given to fuel line diameter and length, as well as the type of application. Understanding the relationship between fuel line size and pressure drop is crucial to designing an effective fuel system.

Fuel injection system components
The fundamental function of a fuel injection system is to spray pressurised fuel into the engine. The system must determine the appropriate amount of fuel to be supplied and control the fuel flow to supply this amount. The components of a fuel injection system can be divided into low-pressure and high-pressure sides.
The low-pressure side of the fuel system consists of the fuel tank, one or more fuel supply pumps, and one or more fuel filters. The fuel tank serves as the reservoir for fuel storage, maintaining its temperature below the flashpoint while dissipating heat from the engine. It is corrosion-resistant and leakproof, with measures to prevent pressure buildup. The fuel supply pump (lift pump) draws the fuel from the tank and delivers it to the high-pressure pump. It ensures sufficient fuel delivery for cooling engine components and maintaining consistent fuel temperature throughout the system. Many fuel systems also contain coolers and/or heaters to better control fuel temperature. A fuel filter is a vital component that protects the engine from harmful debris by screening out dirt and rust particles from the fuel.
The high-pressure side components include a high-pressure pump, accumulator, fuel injector, and fuel injector nozzle. The high-pressure pump pressurises the fuel, which is then conveyed evenly to the engine's cylinders through a fuel rail. The fuel injector is effectively a spray nozzle that performs the final stage in the delivery of fuel into the engine. The accumulator has a high-pressure relief valve to maintain pressure and return excess fuel to the fuel tank.
The fuel injection system uses an Engine Control Unit (ECU) to manage the injection process based on inputs from internal sensors. The ECU controls the timing and amount of fuel injected, adjusting the fuel-to-air ratio to achieve ideal engine performance and efficiency.
The size of the fuel line is an important consideration, as it has a direct effect on the amount of fuel pressure drop your fuel system will experience. EFI kits are rated by the maximum horsepower they support, and choosing a kit that is too big will result in poor idle and bad throttle response.
