Fuel rail leaking at injectors.

[VistaBlueS197]

I just installed brand new fuel rails from fore and brand new DW injectors and every one of them is leaking. Any thoughts, experience, advise anyone has on how to fix would be greatly appreciated.

Most common thing overlooked is lubing the O-rings. Not doing so can cause them to tear.
Next is not having everything seated properly or having the right height injector for the rail setup.

Yeah. Get a jar of vasoline. Lube em up and they all slip together nice and easy.

And disregard all comments about using it to fuck your car when no one's around

I had this problem and it was because I had over tighten the rail with an injector that was the wrong height. A few spacers later and it was fixed. And yes, lube is important.

Wrong size injectors. If they are all leaking the injectors are probably the wrong size. Or the fuel rail is not bolted down properly but that would be your first look see so I don't think that would be it.

Put your old injectors in there. I bet they won't leak.

Angel got it figured out, they just needed relubed and reseated as they weren't in all the way.

Thanks for helping. New injectors, new rails and not enough lube was the problem.
