How to identify DAVCO Fuel Pro and Diesel Pro housings and pick the correct fuel/water separator element.
Identify the housing
DAVCO Fuel Pro and Diesel Pro systems combine particulate filtration with water separation. The wrong element length or seal can cause a no-start or leak.
- Look for the model tag on the Fuel Pro / Diesel Pro unit
- Note the bowl style and whether the unit takes a standard or long element
- Photograph the current cartridge part number before removal
Common elements
- FS20083 — Fuel Pro 485/487/488 standard-length EleMax element
- FS19764 — Volvo/Mack Fuel Pro style applications
- FS19765 — Kenworth/Peterbilt Fuel Pro / Diesel Pro applications
- FS20313 — Volvo/Mack EleMax separator on listed D11/D13 and MP7/MP8 applications
Confirm the application
When in doubt, share a photo of the housing tag and current element with CORALFLY support. Verify the exact part before ordering.
