At Randwick Auto Electrical we can service all your Electronic Fuel Injector needs. Don't buy new until you have yours Tested on our Programmable Test Stand. We can also Ultrasonically Clean, Flow Match, Leak Check, and Repair your injectors.

Since your car was new, dirt, varnishes, and carbon deposits have been forming in your vehicle's fuel system, on the intake valves and in the combustion areas. These build-ups can rob your car of performance.

Some of the symptoms related to carbon build-up are engine pinging, hesitation, poor acceleration, lack of power, repeated stalling when cold, poor performance when cold, rough idle, and poor fuel economy. These build-ups, if left untreated may lead to costly engine repairs.

Our Carbon Cleaning System is a revolutionary new process that will clean your vehicle's fuel system, including injectors, and remove harmful carbon deposits. This system utilises a unique cleaning solution which will not damage your vehicle's sophisticated engine components

How does fuel injection work?

Fuel injection replaced carburetion as the principal form of fuel/air delivery to vehicles in the mid 1980s. The simple, efficient design offered a new standard of reliability and efficiency by delivering fuel in varying volume and frequency - a process that would become more sophisticated as electronics replaced mechanical components within the injection systems.

With a petrol engine, fuel is transferred via an electronic pump known as a fuel pump. This fuel subsequently passes though a filter that removes most contaminates that have entered (or corroded from) the fuel tank.

This filtered fuel then enters one end of a common feeding tube for an engine's fuel injectors called a fuel rail. The other end of this rail is met by a pipe that leads back to the fuel tank - called a return pipe. This pipe contains a fuel pressure regulator (essentially a resistor, or blockage) that ensures all fuel within the fuel rail is kept at a constant pressure (essential for precise metering of fuel).

The engine's injectors 'feed' from this pressurised fuel delivery circuit.
