I'd be worried about the powder coating process buggering the PD up and making it prone to leak - I believe the powder coat process cooks the parts in an oven at like 400*F? You can reinstall the PD/rails, and before putting the UIM and everything else back on, pressurize the fuel system (jumper the yellow connector by the passenger side strut tower per the FSM) and check for leaks before ordering a new parts.

I've had the car running, but haven't taken it above 3k RPMs. The only leak I've ever seen was simply the front secondary injector not being seated correctly in the o-ring/grommet on the intake. But, I'm guessing that the real test on the dampener is when the secondaries are firing under normal driving conditions.

I was reading last night about banjo bolts and differences between S4 and S5 rails. Also spent a little bit of time reading about difference between rotary dampeners compared to piston engine dampeners. I've got a friend with a S4 TII with a blown engine. I may buy his secondary rail to have as a backup. I was pricing Aeromotive and AEM FPRs last night. You can see where this is leading....but I still need to read more before I can talk intelligently about it.
