Leaky fuel injector Options

[Keith V]

Hello All,
I started my car yesterday, and could smell gas. I discovered a leaky injector. I have extra new seals for each injector. Can you give me any advise for replaceing the seals?

Thank you.

For the most part, the injector seals are there to keep air from leaking into the manifold, not fuel from leaking out. Fuel leaks are more likely to be in the injector itself, either between the pintle cap and the metal body, or between the metal plug body and the other plastic bits. Or, as Mike points out, the short hoses between the manifold and the injector can leak. This is the most likely leak around the injector.

Some shops seem to be able to replace the pintle caps (they are available from certain parts sellers if you know where to look and how to ask), but for the most part the fix is to replace the leaking injector.

Try the seals, but be prepared that you might have to replace the whole injector.
