Doing a lot of reading on my new (to me) 2003 360. Been reading up on maintenance and issues that crop up with these cars, and was wondering if there are any known "preventative" items that I should consider replacing? For instance, it sounds like the factory 30amp F1 relay has an upgraded 40amp version, and it sounds like that's something worth swapping out since they are easy to get to and if they fail you can damage your F1 pump (looks like Recambi has an 155437A upgraded part that's not very expensive). Also seems like the F1 pump itself can be replaced with an Alfa unit that doesn't require draining the system. Watched a video and that seems pretty straightforward. Anything else I should be looking at along these lines - known failure points that could be addressed early? Thanks!
