They are not brake lines here, guys. It's not a simple double flair.
The nuts are not thin brass, they are thick steel and don't need line wrenches.
They ARE the injectors, that send the fuel to the nozzles in the cylinder head
The lines can fail from years of 20,000 pound, pulses.
To the original poster, are you sure they all leak or is one spraying on the others. I had to slip cardboard between mine, to find the fine mist leak.
