The number 3 injecter seems to be failing to supply fuel is my guess,Ive replaced the line 3 times.It seems now that Ive got a plugged up injector thats causing the pressurized fuel to find the weakest way out and thats at this connection .No other lines are the problem ,just this one .I know 2 things about this issue ,its not an o-ring leak ,2 ,its not that the lines are not tight enough.I did have some fuel filters clogging after finding rust in the tank.Cleaned out the tank and lines ,then replaced filters . It takes driving the car 200 miles plus then bingo back to square one ,has anyone had an injector fail like this one discribed?It will be replaced as my next step.
