Cummins Fuel Water Separators
Fleetguard FS20074 Fuel Water Separator
The Fleetguard FS20074 fuel water separator is a spin-on primary separator with a drain, listed for Cummins QSL and Cummins Power Generation engines and common on John Deere tractors. Which application is yours depends on the engine build and the installed position, not on the separator number alone.

What the FS20074 Is, and Where It Sits
The FS20074 is a fuel/water separator in spin-on form. It sits in the pre-filter position, ahead of the final-stage fuel filter, and removes bulk water and particulates before they reach the injection pump and injectors.
The drain bowl is the point: it lets a mechanic remove accumulated water at service rather than wait for a restricted element. The position decides the fit, not the number. The same separator number can sit on different builds, and the same build can carry a different separator across production years.
Engine model & build
Provide the engine maker, model and full serial or build number. The model name alone does not confirm fitment.
Installed filter position
Identify the filter head it came from and whether a water separator sits upstream.
Complete old part number
Send the full number printed on the removed element, including any suffix. If the records disagree, send all three for review.
FS20074 Cross-References Are Candidates, Not Confirmations
The FS20074 crosses to a set of numbers across brands. Treat each as a candidate to check against the engine build and the installed position.

| Mann | WK8179 | Cross-listed element |
| Hifi / JURA | SN70270 | Cross-listed element |
| WIX | WF10128 | Cross-listed separator |

John Deere vs Cummins: Two FS20074 Application Routes
The FS20074 surfaces most often on John Deere tractors in the 6M and 6030 series, under John Deere numbers such as RE546336 and RE529644. The same number is also cross-listed for Cummins QSL engines and Cummins Power Generation generator sets.
That split is the useful information. The number alone does not tell you which route is yours. Confirm the engine maker, model and full serial, and the parts record for that build, before treating either application as settled.
A cross-reference is a shortlist, not a statement of equivalence.

Request a QuoteFrequently Asked Questions
What does the Fleetguard FS20074 fit?
It is a primary fuel/water separator. Its listings lean John Deere 6M and 6030 tractors, and it is cross-listed for Cummins QSL and Cummins Power Generation engines. Confirm by engine serial.
What does the FS20074 cross to?
Candidate references include Baldwin BF46045-D, Donaldson P551434, Mann WK8179, WIX WF10128, Hifi SN70270 and John Deere RE-series numbers. Treat each as a candidate to check.
Is the FS20074 the same as the FS19977?
They are close in size and often sit on the same cross-reference row, so one may be a supersession of the other. Confirm the complete number against the parts record.
Is the FS20074 the same as the FS1098?
No. FS1098 is a much larger separator for a different application. The two are not interchangeable.
Is the FS20074 a primary or final-stage filter?
Primary. It sits in the pre-filter position ahead of the final-stage fuel filter, with a drain bowl for removing water.
Confirm the Number, Then Confirm the Build
The Fleetguard FS20074 fuel water separator is quoted against a build and an installed position, in that order: the number finds a candidate separator, and the build and the position decide. Send the engine model, build number, and the number off the separator you are replacing. We will confirm the offered item, its maker, complete number and delivery terms.
