Hi Martin,
is it the return springs for the fuel elements inside the pump?
Remove the side cover (2 screws) and spray the elements with some WD40 (or similar). Wait for some hours to let it work.
Try to force the rack sideways by using a flat screwdriver (or similar) where I have put the arrow on the picture.
The rack should easily move freely to right, and return to the left automatically when you remove the screwdriver.
If the rack do not return automatically, you have 1 or more stuck elements. This happens if the engine stands still for a longer period.
If this is the case: Keep spraying the elements with WD40, and try forcing the rack back and forth until it moves freely.
