fuel leak, what parts do i need?
the bug has a fuel leak and is going in to investigate it soon. i have bought a spare set of fuel rails and also a service kit for the injectors. do the injectors have an additional set of seals to fit into the rails or just the ones that come in the service kit? im trying to get all the bits i might need beforehand to make it easier. i also have a inlet manifold gasket set and a throttle body gasket (this is needing done anyway). any other bits i might need to replace when we are in there? thanks for any suggestions lads.

there's an o-ring around the upper body of the injector that seals against the fuel rail.
There's also a rubber do-nut thing that sits around the lower injector body, which seals against the inlet manifold (or the tgv housing on the bug if it's a wrx).
I've had the o-ring that seals the FPR to the rail leak on me, perhaps make sure it's not that thing that leaks (should be reasonably easy to see, IIRC).

thanks henrik for the ideas, it leaks on initial startup quite badly to the point there is a little puddle of fuel on top of the block just behind and underneath the manifold in front of the intercooler where the bung is for cylinder 3. some logging shows it removes the fuel through the rev range when driving. so its at the drivers side at least i know that lol, mechanic will have fun finding it as im guessing it would show itself better when pressurised but of course it will be in bits.
