If you are searching for an FS20083 cross reference, you may have an old filter in hand and need a replacement, or you are checking which part numbers cover the same fuel water separator. The most important fact comes first: the FS20083 is an older Fleetguard number that has been superseded by the FS20385. This guide explains what the FS20083 is, which numbers appear in cross-reference data, and how to avoid ordering the wrong filter.
IXIN Filter has made filters since 2010, including a wide range of fuel filters for trucks, buses, construction and agricultural machinery. The checks below come from questions our buyers ask every week.
What Is the FS20083 Fuel Water Separator?
The FS20083 is a cartridge-style fuel and water separator element for Davco Fuel Pro and Diesel Pro fuel processors. Published data lists these dimensions:
| Attribute | Detail |
|---|---|
| Filter Type | Fuel / water separator cartridge |
| Housing | Davco Fuel Pro 485, 487, 488 |
| Overall Height | 228.5 mm (8.99 in) |
| Largest Outside Diameter | 154.4 mm (6.08 in) |
| Largest End Inside Diameter | 62.6 mm (2.46 in) |
| Gasket Inside Diameter | 66 mm (2.61 in) |
Cross-reference data links it to Detroit Diesel DD13, DD15 and DD16 engines, Cummins ISX12, ISX15 and X-series engines, and Navistar A26 engines, always with a compatible Fuel Pro housing.
FS20083 Cross Reference Table
The table lists part numbers that appear together in public cross-reference data. Use it as a starting point, not as a guarantee.
| Brand | Part Number |
|---|---|
| Fleetguard | FS20083 (older) / FS20385 (current) |
| Detroit Diesel | A0000905051 / A0001485007 / A485007 |
| Freightliner | A485007 / 485007 |
| Baldwin | PF46145 |
| Donaldson | P580710 |
| Luber-finer | L20083F |
| Carquest | 96811 |
Reference numbers are listed for identification only. All brand names belong to their respective owners, and IXIN is not affiliated with them. One source lists a different Baldwin number for the FS20083, so confirm the exact match with your supplier.
FS20083 vs FS20385: What Changed?
Many buyers search for the FS20083 because it is printed on the old filter. Sources describe the FS20385 as the current replacement, built for the same Fuel Pro housing. Some data shows a very small difference in listed height (about 8.99 in versus 9.04 in), so always compare the physical filter before a bulk order.
If you need the current part, see our FS20385 fuel water separator page.
How to Use an FS20083 Cross Reference Safely
A cross reference shows which part numbers other sources have matched. It does not prove that two filters are identical. Follow these steps each time.
Step 1: Start from the number on the old filter
Read the number printed on the filter you are replacing. If it says FS20083, search for it in the table above. If your number is missing, send it to your supplier instead of guessing.
Step 2: Confirm the housing
This filter is a cartridge, so the housing decides whether it fits. Check that your truck has a Davco Fuel Pro 485, 487 or 488 housing before ordering.
Step 3: Compare dimensions, not only part numbers
Measure the height, outside diameter and gasket size of the old element, and compare them with the published data. A small difference can stop the cartridge from sealing.
Step 4: Check the application
Confirm the engine, model year and truck model. Detroit trucks can use more than one fuel water separator. For example, the FS19915 is a spin-on separator on the Detroit fuel and coolant module, while the FS20083 is a cartridge for the Fuel Pro housing.
Step 5: Ask for a sample or a drawing
For bulk orders, ask for a drawing and a sample, then test-fit the sample before placing a larger order.
Common Mistakes When Using an FS20083 Cross Reference
Even experienced buyers make these errors:
- Ordering the old number only: the FS20083 is superseded, so check the current number as well
- Skipping the housing check: a cartridge only works in its own housing
- Mixing similar separators: FS20083, FS20385, FS19915 and FS19624 are different parts for different positions and housings
- Trusting one source only: cross-reference sites sometimes disagree, so compare at least two
- Treating cross references as guarantees: they are a guide, and you are responsible for confirming fit
For another example of the same approach, see our fuel filter cross reference guide and our P637453 cross reference for air filters.
Why Buyers Choose a Factory-Direct Replacement
Distributors and fleets often replace branded filters with factory-direct alternatives because:
- One replacement item can cover several brand numbers, which simplifies inventory
- Lead times are shorter when you deal with the manufacturer
- Filter paper, metal thickness and packaging can be adjusted to your market
- Pricing is more predictable on repeat orders
When you compare suppliers, look for test data, sample support and clear fitment information. Our guides on how to audit a truck filter supplier in China before placing an order and how to choose an OEM truck filter factory explain what to ask for.
