We have an 1985 Ford Lariat With 6.9 the only mod is after market turbo, this is a father son project that is also a daily runner. We have rebuilt this engine and are still trouble shooting some problems, the biggest one is the leaking of fuel around the injectors, we have installed an injector kit so all the o-rings are new as well as hoses and clamps, could there be to much pressure in these lines? All indications from other forums say the engine would not run or run rough if this we're the case, but she runs sweet. Thank You for any suggestions.

 

did u lube the o-rings before you put it back together ?? they could have torn hence the leaking... scott

 

What johnson mentioned you should lube the orings with vasaline or even motor oil so you dont roll the o ring or tear it.

 

Yes I did lube them so they would slide on easy, I keep a tube of Vaseline for just such an occasion, thank you for the response.

 

Ok so this problem is solved, I purchased another kit and did it all over again, the first kit had misfitting o-rings, they were to large. I tore it all apart twice and it still leaked so I decided to get another kit, this one was built a little different and the o-rings fit tighter, I had bought the first kit online, the second from a local parts dealer? thanks for the suggestions!
