Defects and Damage
I found rust in the fuel tank — does it have to be replaced?
What decides it is not whether rust is visible but whether it has taken section out of the tank wall. Surface oxidation can be cleaned and protected; pitting deepening in the base will eventually perforate.
Why it works this way
The decision needs a borescope look at the inside and, where possible, a thickness reading. A judgement made by eye misleads here more often than anywhere else on the boat.
