It is essential to know that the injectors on petrol and diesel engines are different, in fact, 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 F 150 : The different leaks
It should be said that injector leaks on a Ford F 150 equipped with a petrol engine are rather infrequent. 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:

On these models, the pressure is more than 10 times higher than on the direct injection of car petrol engines, reaching 1800 to 2000 bars.
Leaking injector on diesel Ford F 150 : The different leaks

Leaking injector on my Ford F 150 , how to fix the leak
And to finish, we’re going to take a look at how to fix a leaking injector on your car. Oftentimes a leak is associated, as we have seen previously, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is monumental, specifically on diesel engines. So you will have to take some precautions:
- Lower the pressure before any work is done…
- Masking you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Regarding the repair part of your leak, it will frequently be restricted to swapping the seals that have failed:
- Find the source of the leak
- Take apart the injector in question
- Change the corresponding seal kit
