MD2030 Which Volvo Filter? 3581621 or 3840525
I have seen on volvo parts lists, that the proper filter is 3840525.
The filter that was on my boat when I bought it (second hand) is 3581621.
I've also seen on web searches that 3581621 is the proper filter.
The gasket size seems similar (although not exact) but the biggest difference is 3581621 is about twice as long as 3840525 is.
Which one do I use??
