When we got our B32 there was a supply of Volvo filters, however I’m working through them .
For the VP 2020 ( pretty sure the 2030 will be the same), the primary fuel filter / water seprator should be Fram C1191 PL ( This is the ubiqutous CAV fuel filer fitted on just about every truck and big marine engine like Perkins)
For the oil filter try PH 2870 .
The secondary fuel filter looks like P4186 or FF 167a.
If you go to a motor factor that supplies trucks and commercial stuff they will be able to supply or give you an alternative.
Obviously it’s a good idea if you can take in the old ones as samples first time.
Be preparred for a shock at how little you have to pay compared to the VP prices.
