Q45 Fuel Rail Seals, Fuel Injectors

[shadedoc]

Looks like I'm going to be pulling the plennum (again@#$!!). I've got a leaking injector code, and the FSM says to pull the fuel rail out and visualy inspect while under pressure. I also had fuel smell when it got cold this winter, so I'll be replacing the fuel injector o-rings at this time. Has anyone had experience replacing the fuel rail to manifold seals? Are these a potential area for leakage?

Potential area of air [vacuum leakage]. In a 12 year old car EVERY piece of rubber [hoses and seals/bushings] should have been replaced by now........why cars have depreciated down to 5% of new MSRP in inflated dollars.

Once the fuel rail is out, are these just drop-in seal, or is there more involved? From pictures, they look like they just "pop" in.
