Oil Filter Compatible?

I have in my stock a filter from my 93, a Fleetguard LF3349.

In the dodgeram website it mentions an LF 3959 that supersedes the filter I have for all model years.

Can I use this filter or not?? I can't see alot of difference in the 12V engines with respect to oil filters or am I just being short sighted?

Put the call in to Cummins Western Canada and they confirmed that the LF3349 is useable on the 12 V engine. The only change was going to the 24V...

FYI..

Take it from one who knows absolutely for certain. The LF3349 is okay but there were customer complaints about that product backing off and leaking. After some field testing with the largest B/ISB fleet in the world, FedEx with over 24,000 units, it was decided to beef up the filter shell and gasket retainer. So the LF3959 was born. For better filtration, the LF3894 with Stratapore was released for Dodge Cummins applications. Since DaimlerChrysler elected not to change the filter spud (threaded post), that made the latest filtration backward compatible with the Generation 2, and Generation 1 engines as well.

The guys at Cummins told me the LF 3959 case was beefed up because of very high oil pressures on start up on 24 valve engines that split filters and that the LF3349 was just fine for 12 valves.
