Another good advice: get the proper VDO fuel level cylinder in 280mm length.
Costs some £50,- and takes few minutes for exchange. You can do it yourself.
The 240 mm cylinder is compltely useless. It's such a shame Morgan supplies the TW with the wrong unit.
Example: ( but you need 54??mm diameter / have to check )
