How do you know if your fuel system needs to be repaired?
The fuel system of a vehicle has many elements to it such as fuel filters, fuel injectors, fuel pressure regulator, fuel pump and fuel tank, turbocharger, throttle body and TPS and more. If faulty, symptoms of each component will vary but keep an eye on these common signs that can suggest your fuel system needs a repair or replacement.
An indicator of a faulty fuel pump is a sputtering engine — especially during higher speeds. Continually driving at high speeds and experiencing sudden engine sputtering could indicate a fuel pump issue.
If you notice that the engine runs rough, with abrupt power peaks along with poor fuel economy then this can suggest an issue with the fuel injectors.
Strong smell of fuel
A sudden strong smell from the engine bay along with lower than usual fuel economy can point towards a faulty fuel injector or a malfunctioning fuel pressure regulator.
Difficulty starting the car
The car will struggle to start and run because the fuel pump cannot push enough fuel through to the engine. When a fuel pump wears out, it loses its pressure, starving the engine of fuel.
Frequently asked questions about fuel system repair cost
Is it worth replacing the fuel pump?
Replacing a fuel pump can be expensive but it’s an important component of the fuel system that connects the fuel tank to the engine. Due to continuous use, the fuel pump can wear and eventually fail, resulting in an unstable flow of fuel to the engine.
If you experience problems with the fuel system it is advisable to have the fuel system and the fuel pump inspected and, if necessary, have the fuel pump replaced.
Can you drive with a clogged fuel filter?
While you technically can drive with a clogged fuel filter for a short period of time, keep in mind that it will likely cause further damage to the fuel system. The fuel filter is responsible for filtering out impurities in the fuel, and if it is clogged, it can cause your car to run poorly, and it can damage your car's components. It is best to replace a clogged fuel filter so as to cause minimal damage to the engine.
