The original Stbd. fuel tank appeared to be in pretty good shape despite the fact that it was foamed in. The lid did have a slight bulge and it was in dire need of serious cleaning.
If, however, anything happened to it in the future (pinhole leak etc.) it would be a major saga to replace it. The decision was therefore made to remove it now, while the engine room was empty.
It can be pried inwards if the front of the fiberglass box is cut away. It is foamed along about 1/3 of its bottom and outboard side. It can only be removed via the engine room lid.
Still way too hot for this nonsense....
