❓ FAQ
As a complete assembly. The box holds the filter head, the 30 micron element, the clear collection bowl with its drain tap, two hose tail fittings and two plugs, so only the hoses have to be supplied.
Yes. The head has more than one inlet and outlet, so the hoses can run on the same side or on opposite sides. Choose the pair that clears the chassis rail before tightening anything.
300 litres per hour including return flow, which covers diesel engines up to about 350 hp. Above that figure the element becomes the restriction and a larger housing is the right choice.
Look at the clear bowl. As soon as a water layer is visible under the element, open the drain tap at the bottom and run it until clean diesel appears, then close it.
The element inside is 31863, 91 mm long, and it can be changed without replacing the head or the bowl. Baldwin lists the same element as BF7783-D.

Product Overview
31863 is a complete fuel filter assembly, 269 mm (10.6 in) tall, that fits ahead of the factory filter as a primary water separator on diesel engines up to 300 litres per hour.
