It is not correct.

Who wants to own a motor that goes into "save ME not the passengers" mode... over every little piddly thing?   And even if it does go into safe mode simply turning the key off then back on resets it.  No computer re-programming required.

Casey,  you either have a EFI or carb Merc.  The system on the Optimax DFI is different.  

In your case, yes only the cap needs replaced, not the tank.  And that system does not have the washer adhered to the float like the Optimax oil reservoir.  The actual sensors on those, like yours, never fail, the caps just crack and cause leaks.
