For a US fleet buying service cartridges for an identified DAVCO Fuel Pro 382 with a Plus cover, Baldwin PF7930, Donaldson P550851 and Fleetguard FS19765 form a useful manufacturer-documented shortlist. They are not automatically interchangeable on every 382 installation. First establish the installed cover, engine requirement and approved reference; then qualify each offered cartridge against that baseline. This comparison explains why the three numbers appear together, where the documentation stops short of replacement approval, and which ordering differences deserve attention. “Top” describes the evidence-backed shortlist, presented alphabetically by brand, not an independent filtration-performance ranking.
This is a replenishment decision: the fleet intends to retain its approved housing and buy another service cartridge. It is not choosing a complete separator, adding a heater or changing the fuel-system layout. If the proposed purchase includes a new head, bowl, pump or installation package, the pre-filter assembly comparison addresses that different decision.
Keep the starting reference visible on every quotation. A request that says only “DAVCO 382 filter” allows a supplier to answer a different question from the one the workshop intended.
Brand | Cartridge | Documented starting point |
|---|---|---|
Baldwin | PF7930 | Named replacement-chart entries |
Donaldson | P550851 | Plus-size cartridge specification |
Fleetguard | FS19765 | DAVCO application-chart reference |
Those are three ways to investigate a replacement, not three identical technical approvals. A manufacturer cross-reference nominates a candidate. The fleet's current application requirement decides whether that candidate can be purchased for a particular vehicle.
DAVCO's F3105 application chart, Revision A15 dated December 10, 2025, separates Plus-cover configurations from the older Standard-cover arrangement. Its illustrations distinguish the covers and collars; the named processor alone does not resolve that difference.
The Plus-cover table places FS19765 in a 25-micron group and FS19764 in a 10-micron group. These are different rows with application qualifications, not two spelling variants of the same cartridge. The chart also directs users to the latest engine-manufacturer documentation.
For purchasing, record the processor identification, clear cover/collar photographs, the complete current cartridge number and the applicable engine requirement. If any of these disagree, hold the proposed substitution. Do not change the cover simply to accommodate the cheapest candidate on the quote, and do not treat a cartridge that physically enters the housing as an approved filtration choice.
Baldwin's DAVCO replacement guide, Form 584 R2/22, places PF7930 alongside FS19765 and P550851 in several specified Plus-cover application rows. That is direct manufacturer evidence for including PF7930 in this comparison. It is not a common-condition test proving identical efficiency, water separation or service life.
For a US truck-parts enquiry, Baldwin also provides application-specific catalogue context. Its On-Highway Form 607, revision June 2024, associates PF7930 with FS19765 in a Kenworth T680/Cummins ISX 15.0 listing qualified to 2013–2018. The model-year qualification matters: do not turn that entry into coverage for every T680, every ISX generation or an unidentified fuel processor.
Ask the quoting party to identify the current PF7930 specification and the exact application used to approve the order. Retain the catalogue edition, rather than keeping only a screenshot of the part number.
The brochure linked from Donaldson's current P550851 product page is F111295 ENG, October 2023. It lists P550851 as a Plus-size Fuel Pro 380/382 EleMax cartridge, with a stated efficiency of 99% at 25 microns, and specifies a Plus-size cover and collar. Its cross-reference section maps PF7930 to P550851.
This provides a specific source for the product and housing boundary. It does not establish a three-brand performance winner. The brochure's rating should remain attached to its product, edition and stated basis; it cannot be pasted into the PF7930 or FS19765 quotation as their measured result.
Request current product data for the offered P550851 and confirmation of the retained assembly. Do not substitute a neighboring Donaldson number because a retailer puts several of them in the same cross-reference block.
If FS19765 is the documented, approved service reference for the retained assembly, preserve that complete number while investigating other brands. It gives the parts counter a concrete starting point instead of an open-ended request for a cartridge of roughly similar size.
A current US procurement route is visible on Komatsu America's FS19765 listing, which identifies the all-makes Fleetguard line and links to ordering and dealer options. This is evidence of a commercial enquiry path in the US market. It does not mean Komatsu manufactures the filter, that a particular dealer has stock, or that the part is approved for every truck in this comparison.
Ask for the supplied brand, full part number, included service items and delivery terms in writing. Keep an offered alternative distinct from the requested item until it has been approved; a quote should not silently replace one with the other.
Form 584's PACCAR section includes a row placing PF7930, FS19764 and a 25-micron description together. That conflicts with the FS19764 filtration-group distinction in DAVCO's A15 chart. This comparison excludes that row as a basis for approval; it does not silently change the printed number or decide that the two ratings are equivalent.
If that is the row being used to justify your order, obtain a current, application-specific answer from the responsible manufacturer or engine support channel. Keep the conflicting source with the enquiry so the response addresses the actual discrepancy. A general “yes, it crosses” answer leaves the problem unresolved.
The June 2024 Baldwin on-highway guide separately lists PF46094 against FS19765G for a 2021 Peterbilt 579/PACCAR MX-13 application. Do not remove the G and treat that as the FS19765/PF7930 combination discussed here. Nor does a broad cross-reference table that sends multiple Baldwin numbers to one Donaldson number prove that those Baldwin products are mutually interchangeable.
The purchasing consequence is straightforward: preserve suffixes in the enquiry, supplier acknowledgement and receiving record. Any claimed supersession needs a current written reference showing the direction and applicable configuration, not an inference from a shared search result.
Once a candidate is eligible, compare what will arrive. One Missouri seller's PF7930 listing, for example, is explicitly a case of six. A case price and an each-price are not directly comparable. A catalogue entry or local listing also does not establish the quantity available for your delivery date.
Request an itemized offer that states the exact brand/reference, number of cartridges, supplied seals or other service items, shipment quantity and destination ZIP code. Ask which items are immediately available and which would be ordered in. Keep any substitute proposal on a separate line so a stock shortage does not change the approved part unnoticed.
The useful outcome is a repeatable order for a defined vehicle group. It is not a warehouse bin labelled with every number a cross-reference search happened to return. Separate unapproved alternatives from released stock, and retain the application decision when the procurement team changes vendors.
For an aftermarket sourcing enquiry, review Elecdura's diesel fuel-filter category and use this article's enquiry form to provide the processor identification, cover photographs, exact approved reference, engine details, quantity and destination. The category does not establish that Elecdura stocks these branded cartridges, is an authorized distributor, or supplies an approved interchangeable product. Any proposed aftermarket item needs its own identity and evidence.
Use the vehicle and engine identification, processor markings, retained cover/collar photographs and service history to recover the approved reference with the responsible parts or technical support team. Keep the unknown number marked unknown. Photographic similarity to a listed PF7930, P550851 or FS19765 can help frame that enquiry, but should not authorize a bulk replacement order.
Ask for the current manufacturer document for the exact offered product and the application approval behind the change. A better-sounding efficiency, media or service-life claim is not enough if it uses different test conditions or describes another filter. Until the responsible technical party resolves the change, purchase against the existing approved requirement rather than rewriting it to match the offer.
Resolve the service package before release. Have the supplier identify what is included with the quoted cartridge and what must be obtained separately for the documented service procedure. Record those items on the order. Otherwise an apparently complete replenishment shipment can leave the workshop waiting for an omitted component; the presence of seals in a product photograph does not settle the supplied scope.
Keep the maker or offered brand and its actual part number separate from the reference it is proposed to replace. Request application evidence for that item; do not label it as genuine Baldwin, Donaldson or Fleetguard because it cites their numbers. Clear identification allows the buyer to evaluate the proposal on its own evidence and keeps later receiving or warranty discussions tied to the part actually supplied.
