Yes. FF5706 crosses to Cummins 5262311 and 5283169, Donaldson P555706 and Volkswagen 2P0127177. The thread is M100 x 4-7H SPL Butt, the can is 212.85 mm (8.38 in) tall and the gasket bore is 57 mm (2.244 in).

FF5706 is the fuel filter that traps solid particles at 20 micron with 95% efficiency and coalesces free water so the bowl or drain can drop it out. It is not a dedicated separator unit, so it works alongside the water trap on the filter head rather than replacing it.

Follow the torque printed on the filter housing or the service manual for the specific engine. As a working rule, lubricate the gasket, spin the can on until the gasket contacts the head, then tighten a further three quarters of a turn by hand or with a strap wrench.

The ABS housing and cellulose media are compatible with diesel and common biodiesel blends, but water pickup rises with biodiesel content. Drain the separator more often and shorten the filter interval if the truck runs high-blend fuel in humid conditions.
