Not sure, I haven't played with your particular fuel rail much.
On a TPI, the Fuel injectors held in with O-rings on both sides if I remember correctly. WE had some gunk in the inside of one of the fittings that, I am not sure how it got there, kept the O-Rings from sealing. Would eventually create a leak after enough times at Max Pressure (WOT)... once it had moved... it would leak. We remedied this by cleaning out the rail sealing areas with some alchol and Q-tips. Let them dry, put a slight bit of oil on the O-rings before replacing them and never had the problem again. Can't say this is for sure your issue, but just my experience with a similar problem.
