Can someone help me understand the real difference between Cummins 3934303 and 3918954 oil filter housings? In most cases, 3918954 oil filter housing application is listed as 1994 -1998 and 3934303 oil filter housing application is listed as 1998.5-2002. Is this correct? As far as I understand it, 24 valve blocks are essentially 12 valve blocks, but not vice versa. (I think maybe 2001 is an oddball year?) Is the difference between the oil filter housing applications actually STORM vs non-STORM blocks? It is my understanding 12 valve engines were built with STORM blocks beginning late 1997 model year. My 1998 Dodge 12 valve has a STORM block.
So.....would I use the Cummins 3934303 or the 3918954 oil filter housing on a 4BT?
