So I have a Leaky PD. I'm not to sure about the whole banjo bolt thing, so i'd rather just buy a new fuel rail. But i'd prefer to have a more reliable aftermarket one.
Maybe even one that can work with the stock ecu? Do I ask too much?
Can anybody help me out on this?

 

If you insist on not just replacing the PD with one that doesn't leak, you can buy an S5 rail and bolt that on. The PD is integrated, and less prone to failure.
