A diesel fuel filter replacement program should answer two questions before price comparison: which part number is being replaced, and whether the filter design matches the real machine. This English fallback guide also supports Polish buyers searching for filtr paliwa, filtr paliwa do ciezarowki, filtr oleju or filtr hydrauliczny; for fuel-system sourcing, the focus here is diesel fuel filters and fuel-water separators such as FF5629, FS20190, FS36277, FS1242, FK11011 and 1001044160.
Part numbers to check before ordering
For trucks, construction machinery, generators and agricultural diesel engines, the buyer may need a main fuel filter, pre-filter, water separator or a complete service kit. Keep all part numbers visible in the inquiry so the factory can compare dimensions, sealing, water-drain function and packaging requirements.
| Model | Filter type | Practical buying check |
|---|---|---|
| FF5629 | Diesel fuel filter element | Check OD 95 mm, ID 14 mm, length 144 mm, MAN 51125030061, SINOTRUK 201V125030061 and the existing filter head. |
| FS20190 | Fuel filter / water separator | Check OD 132 mm, ID 46.7 mm, length 254 mm, SINOTRUK WG9925550966 and the water-drain position. |
| FS36277 | Fuel-water separator | Confirm seal, thread, water drainage and diesel service interval before repeat order. |
| FS36259 | Fuel-water separator | Compare engine family, installed filter and reference history. |
| FS1242 | Water separator canister | Check 1-14 UN thread, 1 1/4-10 UN bowl thread, gasket OD/ID and bowl compatibility. |
| FK11011 | Fuel filter service kit | Confirm all elements in the kit and the fleet maintenance interval. |
| 1001044160 | Primary diesel fuel filter | Check WEICHAI WP10, Baudouin 6M21, M20 x 1.5 thread and engine serial number. |
| 4461492 | Secondary fuel filter | Confirm Perkins engine application, gasket and service position. |
| JCB 32007155 | Fuel filter canister | Compare machine model, old filter photos and filter-head connection. |
| Claas 21703110 | Agricultural fuel filter | Consider seasonal dust, fuel quality and replacement schedule. |
| Caterpillar 5234987 | Fuel-water separator | Check height 258 mm, OD 103 mm and references such as SN40858. |
| Donaldson P551425 | Fuel-water separator | Compare OD 80 mm, length 197 mm and cross references such as FS19525 / FS19827. |
Poland search fallback: what should the buyer send?
When a Polish distributor searches for filtr paliwa, the inquiry often arrives with a mixed set of OEM numbers, aftermarket numbers and photos. Send the visible part number, old filter photos, machine model, engine model, target quantity, destination market and packaging request. If the inquiry also includes filtr oleju or filtr hydrauliczny, route those items to the correct oil filter or hydraulic filter category instead of mixing them into a diesel fuel-filter order.
Procurement checklist for distributors
- Do not rely on one cross-reference only: confirm dimensions, thread, gasket, flow direction, water-drain design and working conditions.
- Keep model numbers searchable: FF5629, FS20190, FS36277, FS1242, FK11011 and 1001044160 should appear in visible text, not only in images.
- Ask for sample approval: use samples before repeated orders when the replacement history is not fully confirmed.
- Specify packaging early: neutral carton, private-label carton, label layout and carton marks can affect lead time and MOQ.
OEM and private-label supply

For a reliable quotation, send the target number, current sample or photos, key dimensions, requested carton or label requirements, estimated monthly quantity and destination market. Brand names and part numbers are used only for replacement identification and compatibility checking.
FAQ
Can I order by cross-reference number only?
No. Cross-reference numbers are a starting point. Always confirm dimensions, thread, gasket, water drain, flow direction and real application.
Which models are good first candidates for a fuel-filter program?
Start with searchable and easy-to-verify models such as FF5629, FS20190, FS36277, FS1242, FK11011 and 1001044160, then add the customer’s machine-specific numbers.
Can Precise support private-label fuel filters?
Yes. We can discuss sample approval, packaging, labeling, MOQ and export delivery after technical confirmation.
For broader reference checks, use the Cross-Reference Hub, fuel filter category and water separator category.
