Have experienced similar situation on our car. All I did was to loosen
the clamp on the metal pipe to let it come over further to connect the
displacer. Once the system starts pressurising the displacer hose should
expand and things should start to fit back in place. The main thing to
watch for is that when fully pressurised the rubber hose has room to
move around in the square apeture and isn't hard up against the metal edge.
You should also be aware this LANDCRAB discussion group is now inactive
as we lost the Moderator a few years ago and everyone has now moved over
to the AUSTIN1800 google group.
Cheers,
