What the 26561118 Is, and Where It Sits
The 26561118 is a Perkins fuel filter. Listings describe it as a spin-on — element and housing in one unit, threaded onto a filter head and sealed by a gasket — fitted with an integrated water trap, which gives it a water-separating function at the primary stage. Some sellers describe it as a fuel/water separator. Check the housing you are servicing: a water-separating filter is usually the one with the drain or bowl you service on schedule.
It sits at the primary fuel stage on 500, 1000 and 1100 Series builds, upstream of the final-stage element. Listings call it “primary”, “pre-filter” or “fuel filter with water trap”; the sequence differs by build. Confirm the position and old number, not the label.
26561118 Specifications
We publish only the fields that agree across listings. Thread, dimensions and micron rating are withheld: listings conflict, and a copied figure is not evidence. Those values are confirmed against the manufacturer specification for your build and stated in your quotation.
| Check | What listings say | How to confirm |
|---|---|---|
| Engine-maker number | Perkins 26561118 | Check the Perkins parts record |
| Form | Spin-on with an integrated water trap; some sellers call it a fuel/water separator | Check the housing you are servicing |
| Donaldson cross-reference | P111810 and P550588 both cited | Confirm against the build record |
| MANN-FILTER cross-reference | WK 842 and suffix variants cited | Confirm against the build record |
| Thread, dimensions, micron rating | Not published | Confirmed per quotation |
Three Records That Have to Agree
-
The engine build: maker, model and full serial or build number.
-
The installed position: which housing it came from, and whether a water-separating stage sits upstream.
-
The complete number on the removed filter, including any suffix.
Where the manual, the parts record and the old filter disagree, send all three. A manual can print a number that was correct for a different build; the filter in your hand is evidence.
26561118, 26560143 and 26560145: Similar Numbers, Different Jobs
26560143 is the final-stage fuel filter element — a cartridge, per Perkins — a different position on the same engine families. The engine-model lists overlap, so the series name alone does not separate them. They are not alternatives to one another without a record check.
26560145 is the dedicated fuel/water separator — a separate stage. 26561118 is a fuel filter that also separates water; 26560145 is the separator on its own. If your service includes draining water, you may be servicing one of these two, not the final-stage element.
The trailing digits matter. 26561118, 26560143, 26560145 and 26560608 all circulate in the same generator filter sets, and the cross-reference pair P550587 and P550588 differs by one digit. Transcribe the full number.

Applications, and How a 26561118 Order Is Quoted
Start with the engine, not the vehicle.
Perkins 500 / 1000 / 1100 Series
Applications are engine-led: generator sets, agricultural machinery, plant and marine duty. The same filter appears on equipment lists under New Holland T4–T9 tractor and JCB numbering; confirm those on the machine’s own record, not on the filter’s.
Industrial cross-references also require a check against the machine’s parts record.

Request a QuoteFrequently Asked Questions
What is a Perkins 26561118 fuel filter?
A Perkins spin-on fuel filter listed for 500, 1000 and 1100 Series engines, described with an integrated water trap. The bare number is ambiguous — it appears in unrelated listings — so always pair it with “Perkins fuel filter” when searching or ordering.
Is 26561118 a fuel filter or a fuel/water separator?
A fuel filter that incorporates water separation. It is not the dedicated separator (26560145), which is a separate part. Confirm the position and whether the housing has a drain before ordering.
What is the difference between 26561118 and 26560143?
Different positions on overlapping engine families. 26561118 is the primary spin-on with a water trap; 26560143 is the final-stage element. Confirm by serial and position, not by series name.
Does 26561118 fit a New Holland tractor?
It appears on New Holland T4–T9 tractor lists. Only the engine serial and the installed position confirm it. Send both with the old number.
Confirm the Number, Then Confirm the Build
The Perkins 26561118 fuel filter is quoted against a build, a position and a number, in that order: the number finds a candidate, and the build and old filter decide. Send the engine model, build number and the number printed on the filter you are removing.
