❓ FAQ
The Davco Diesel Pro 245 fuel processor. The element is the service cartridge for that housing, so the processor body stays on the frame rail and only the element is renewed.
No. FS20081 is 101 mm across and fits the Diesel Pro 245 housing, while FS19915 is 148 mm across for a different housing. Check the old element against the diameter on this page before ordering.
10 micron. Water removal runs in three stages: a coalescing layer, a second coalescing area that collapses the droplets, and a hydrophobic barrier that stops what remains.
Because published figures for this part disagree by more than 13 mm, and the element seats on a housing spigot rather than on a measured stack. Compare the old element physically instead of trusting a catalogue number.
Yes, on EPA 2017 engines with the Diesel Pro 245 processor, and the same cartridge also serves the Detroit DD5 and DD8. Fitment follows the housing, so confirm the processor model first.

Description
Product Overview
FS20081 is a fuel water separator element with a 101 mm (3.98 in) outside diameter and a 10 micron rating, built as the replacement cartridge for the Davco Diesel Pro 245 fuel processor. It sits in the housing between the tank and the high-pressure pump, dropping free and emulsified water out of the diesel before the injectors ever see it.
