OK I did this when I put the 550s in - how big of a no no is this I hate to take the whole left side of the motor apart if this isn't fatal ie cause a fuel leak. Can anyone help?
I used Vaseline after Mark (above) suggested it. Previously I had tried about 4 times and failed each time to get a proper deep seating of the injectors into the fuel rail. And each time it leaked.You'll have to cross your fingers I guess? I use good old Vasoline...never failed me yet.
