The nomenclature is variable ..but you're correct in what you say in regard to Amsoil remote mounts. A Dual Guard comes without installed restrictors. That is, it could be used as a dual full flow Cummins if one so desired. The restriction is in the selection of your fittings. I don't see the biasing restrictor valve on the spare parts list, so you can't run a Dual Guard as a combo if I read everything correctly. Well, you can, but it will take awhile for the full flow to accumulate enough loading to make the EaBP get a good % of flow.
