Re: Scenic - has my petrol tank warped?
The casting is there to protect the fuel rail I believe?
They are all mounted to a single rail which is held in place by 2 10mm A/F bolts. Squeeze and release the fuel pipe and then carefully pull the injectors from the inlet manifold. They are held in place by "O" rings get them moving and then a squirt of WD40 or similar will make them easier to pull out.
I don't think you will be able to tell much by looking at the injectors?
Also makes it easier if you lubricate the "O" rings with WD40 on re-assembly.
