That is the primary water separator/filter. There may be a secondary filter on the engine depending on which engine you have. On mine it is on the passenger side of the engine and is easier to reach if you lift the bed up.

We have the same engine (330 ISC) and a 1999 coach. There is only one fuel filter/separator on our coach, located in the rear outside passenger side compartment. Over the years, a number of shops have told us there are two filters (primary and secondary) on the ISC 330 but after looking for the secondary on our coach have concluded that in fact there is only one on ours. Cummins has confirmed that some ISC's had only one.

WRV varied over the years w/one or two filters. My rig has two but others near my serial# have one. I think it had to do w/Cummins and what they had on hand & how soon WRV needed it for assembly. The 2nd filter will be forward on the PS of engine (this is the standard OEM mount, w/the remote filter taking a remote mount kit).
