It is vital to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two sort of engines makes the injection different. The key difference lies in the pressure undergone by the injectors, on a petrol engine it will vary between 3.5 bars for indirect injection and 120 bars for indirect injection.
Leaking injector on a petrol Ford Taurus: The different leaks
It should be noted that injector leaks on a Ford Taurus equipped with a petrol engine are rather rare. This is as a result of the much lower pressure in the petrol intake systems. Even so, there are two sort of leaks:
- Leakage from the top of the injector:
It is conceivable that you have a leak from the top of the injector, this is the portion that is linked to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:

But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is done…
- Covering you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Relating to the repair part of your leak, it will oftentimes be limited to changing the seals that have failed:
- Discover the source of the leak
- Take apart the injector in question
