Volvo Penta MD2030 filter equivalents, also cutlass bearing sizes and fan belt

Keyparts are selling VP equivalent fuel filters for the 2030 at £15 they are from a californian outfit called Sure, filter number SFF6031, this has a Fram equivalent P2367 or a Crosland 370. The oil filter I sourced, using dimensions, as a Crosland 2093, the alternator belt is a Continental 966901 and the Cutlass bearing for bene 351 is 25mm id, 40mm od and 105mm length, the size for a bene 36cc is 30mm id, 40mm od and 104 mm long. these are £30 ish from a bene dealer but i am aware that somebody is supplying them as a std part at a lot less, am trying to refind them and will post it when i do.
