There are owner-operators still pulling a load behind a 1996 Peterbilt 379 with a Cummins N14 under the hood, and there will be for a long time yet. The 855 Big Cam predates them by another decade, but the surviving ones run as hard as anything that came after. Steinberg keeps the FF011 in stock for the same reason the parts counter at any old-school Cummins shop still has a stack on the shelf, because a fleet that runs older equipment runs it well, and the spec on these separators is exactly the same as it was in 1989.
