Fuel injectors are electronic devices that inject pressurised fuel into the combustion chamber of an internal combustion engine. They are commonly used in petrol and diesel engines and have replaced carburetors. Fuel injectors rarely need to be replaced, but ignoring a clogged or failing fuel injector can lead to serious engine damage. If you are confident in knowing your way around an engine, you can replace a fuel injector yourself, but it can be a fiddly process.

Fuel injectors rarely need to be replaced
If you're unsure whether your fuel injector system needs cleaning or replacing, consider its age and condition. If the injectors are old or worn out, a clean may not be sufficient to restore performance and could cause further damage. Removing and replacing a fuel injector can be a fiddly process, so it's only worth attempting if you're confident with car engines. You can find new or used fuel injectors at breaker yards or online.
It's important to note that driving with leaking fuel injectors is dangerous and should be avoided. You'll be able to smell gas and see smoke if this is the case. While it's not an emergency, you should get it fixed within a few days.

Fuel injectors can be replaced at home, but it's a fiddly process
If your fuel injectors are leaking, you'll smell gas and see smoke. In this case, do not drive, as a gas leak can spark a fire. You can continue to drive if your fuel injectors are dirty or damaged, but get them fixed in the next few days. The longer you drive with dirty or damaged fuel injectors, the worse it will be for your engine.
When installing new injectors, it's a good idea to change each of them as a set, even if only one or two need replacing. This ensures each cylinder in your engine gets an equal amount of gas. You can dip the tip of each new injector in a small cup of gasoline.
It may be time-consuming to track down new or used fuel injectors at breaker yards, so it's worth shopping around online.

Fuel injectors are electronic devices that inject pressurised fuel into the combustion chamber
If your fuel injectors are leaking, you should not drive your vehicle as this could spark a fire. You may only need to change your fuel injectors once over a vehicle's entire lifespan. However, ignoring a clogged or failing fuel injector can lead to more serious engine damage and potentially costly repairs. It's important to note that fuel injectors rarely need to be replaced when compared to other vehicle systems. It's much more likely that you've got an issue with your fuel pump, fuel filter, engine oil, or differential if your vehicle is accelerating strangely or you're getting bad mileage.
If you're not sure whether your fuel injector system needs a good cleaning or if it needs to be replaced, consider the age and condition of the injectors. If they are old or worn out, a clean may not be enough to restore performance and could do more damage. Removing and replacing a fuel injector can be a fiddly process, so it's only worth attempting if you're confident in knowing your way around an engine. You'll install your new injectors the same way your current injectors are installed. It's always a good idea to change each of your injectors as a set, even if only one or two of them need replacing. This ensures each cylinder in your engine gets an equal amount of gas.
