Please do not do that to your engine.
The Cummins engine has several unique things that make a remote oil filter ONLY a very bad idea.
One of several issues people have had with any remote filter is starving the engine of oil. If you were to call Amsoil directly and speak with someone with a shard of technical knowledge, they would tell you that they no longer recommend the dual filter remote bypass unit for the cummins engine. They now recommend the stand alone BMK-13 bypass, and say not to block the full flow filter.
The full flow filter has no bypass setting (Almost all remote mount filters do have some kind of bypass setting). And the lines are way too small for transfering all of the oil to the filter and back to the engine.
The best thing in the world you can do is simply add a bypass filter to the oil system so you have to change the filters and oil less often.. I'm assuming you have twins and don't like breaking them apart to change the filter.. If nothing else, consider extending your drain intervals with a very high quality full flow oil filter, synthetic oils, and a bypass filter. Then you can take apart the twins as prevenative maintenance every 15,000-20,000 miles as you replace the oil filters.
Keep a good record using oil analysis along the way, and you should have no problem reaching those types of intervals..
I would highly recommend using the Hastings/Baldwin B50 oil filter and mount. Less then 1/4 the cost of amsoil, and will filter down to 4um.. (red blood cells are 8um for comparison)
