fuel leak

[sculler2x]

I replaced the high pressure fuel lines on my V11 and now I have a fuel leak and it is not the lines or clamps.  When it is cool fuel comes out where the T fitting goes into the injector.  Any ideas on how to stop this?

Is there not an O-ring for that junction? is it both injectors?

There should be O rings at the T fittings. Your local NAPA should have them. It certainly isn't a picnic taking the injectors off. IIRC, there's a circlip that needs to be removed to remove the T fitting at the injector. If you're going to remove the injector for this, it wouldn't hurt to send them in for cleaning at that point. I sent mine to www.lindertech.com, and I think the total cost with shipping was around $80 for the pair. 

Did you use fuel injector clamps when replacing the hoses? They don't dig into the hoses like standard hose clamps do.

It is only the left side and I used the injector clamps. The leak stopped for a while when it was warmer but it started again after 3 days of rain and cold.

The problem is now solved.  I was able to remove the T fitting without removing the injector by releasing the circle clip.  The O-ring was in perfect condition but it was not free to move.  I have seen this before in industrial applications.  I put fuelproof Flourinated  (Krytox) grease on the O-ring and mating surfaces and the leak was stopped.
