A DAVCO Fuel Pro 382 assembly order should identify the chassis configuration and selected water-in-fuel and heating equipment, not just the 382 family name. DAVCO publishes separate Freightliner/Western Star, Navistar, PACCAR and Volvo/Mack configuration pages, and their option references are not identical. For a U.S. fleet replacing complete separators, the useful comparison is therefore which documented configuration belongs to each installation and what the quotation includes. This guide compares those ordering routes without ranking their performance. It does not select replacement filter cartridges, approve a retrofit or establish that assemblies can move between vehicles without further confirmation.
The intended reader is a fleet parts buyer, distributor or workshop coordinator who already knows that the purchase concerns a complete separator. If the requirement is still simply “a fuel filter,” first separate the service item from the installation requirement. The Elecdura fuel-filter catalogue is a starting point for an aftermarket enquiry, not evidence that every DAVCO configuration is stocked or supplied as a genuine branded assembly.
The table below preserves the optional-item references shown on the respective DAVCO pages when reviewed. It is a research comparison, not a complete bill of materials or an interchange chart. A chassis group identifies the relevant catalogue route; it does not identify every vehicle build within that group.
DAVCO configuration page | Listed WIF option | Listed 12 V DC heat option | Listed 120 V AC overnight option |
|---|---|---|---|
103805 | 103708 | 103473 | |
103445 | 103709 | 103473 | |
103806 | 103709 | 103473 | |
103801 | 103708 | 103473 |
WIF means water-in-fuel. These rows demonstrate why a common family description is too broad for purchasing. They do not explain the electrical characteristics of each sensor or establish which harness, connector or installation components accompany an order. The supplier must connect the selected options to the actual complete assembly and vehicle requirement.
Do not use a repeated accessory reference as permission to merge the entire assemblies. Equally, do not conclude from different references alone that a modification is necessary. The next step is identification: obtain the complete assembly record, selected options and applicable installation documentation before deciding what remains the same.
Begin with the separator on the vehicle, not with the catalogue image. Retain the readable model or assembly markings, vehicle identification and photographs showing the separator's connections and installed accessories. If previous workshop modifications are known, describe them. A manufacturer's original chassis configuration and the hardware now installed may require reconciliation.
Illustrative identification guide using a generic separator, not a photograph of a DAVCO Fuel Pro 382. Record the actual unit's markings, connections, mounting and fitted options; pictured geometry does not establish fitment.
Ask the responsible supplier to return the complete proposed assembly identity and explain how it matches that record. An answer containing only a service sensor, heater or cartridge number has not identified the complete replacement. A cross-reference should name what is being cross-referenced and whether any parts are retained or supplied separately.
If markings cannot be read, photographs can help the supplier investigate. They should not become a substitute for an unresolved technical identification. Keep that vehicle's requirement separate from confirmed stock orders until the manufacturer or application-responsible source can identify an appropriate assembly.
Consider a purchasing team with confirmed separator requirements for different truck makes. Its stock system might currently describe every assembly as “DAVCO 382 with heater.” That description hides the differences in the table. Create separate requirement records until the supplier has documented any valid common assembly and its exact installed options.
This is an inventory-control example, not proof that those vehicles need different assemblies in every case. The objective is to make consolidation an evidenced decision. A warehouse naming convention should not decide electrical or mechanical compatibility on behalf of the workshop.
The official configuration pages distinguish DC electric heat, AC overnight heat and, where shown, coolant heat. A buyer should therefore describe the heating arrangement actually required rather than request an unspecified “heated 382.” The procurement task is to preserve the approved system configuration, not to choose a heater from the truck's operating country alone.
Generic illustrations distinguish water-detection and heating option categories; they are not DAVCO accessory photographs, part-identification aids or wiring instructions. Confirm each actual option and its approved combination separately.
For a U.S. depot enquiry involving overnight heating, identify the vehicle requirement and the site's approved power arrangement. Ask which assembly, heater and supporting connection items the offer contains, and which remain the installer's responsibility. The presence of an AC option on a product page does not show that the vehicle or depot is prepared to use it.
For DC heat, confirm the actual approved supply and wiring requirements with the relevant installation documentation. This article gives no fuse size, wire gauge or connection instructions. Do not replace missing electrical information with a generic 12 V label or assume that a previously installed connector is suitable for a different offered assembly.
The Navistar page's specification table lists coolant as optional, while its observed purchase selector lists WIF, DC heat and AC overnight heat without a coolant choice. That difference does not prove that coolant heat is unavailable or included. Refer the two page sections to DAVCO and ask for the applicable configuration and ordering instruction. Until clarified, leave that option unresolved on the enquiry.
Do not copy prices from the selectors into a complete installed-cost comparison. A page price does not settle the selected configuration, all required installation items, freight, account terms or availability for the requested quantity.
A useful order connects the approved technical response to a visible receiving check. Include the exact offered assembly identity, chassis application basis and selected options in the purchase description. Retain the supplier's document revision or dated confirmation rather than keeping only a screenshot of the family page.
Before approval, prepare the following items:
Vehicle and installed separator identification, with any uncertainty or prior modification disclosed.
The supplier's complete assembly number and explicit application confirmation.
Selected WIF and heating configuration, preserving the supplier's exact references.
A list of supplied accessories, retained components and separately required items.
The applicable installation document and the party resolving any wiring, connector or coolant-interface question.
Quantity, U.S. delivery destination, required date and the agreed response to an incorrect or incomplete delivery.
On receipt, compare the carton and assembly identification with the approved order, then check the declared options and included components. If an accessory differs or the assembly identity is absent, stop release for installation and ask for clarification. Receiving photographs document what arrived; they do not independently approve a technical substitution.

A supplier-proposed replacement number should remain visible as a change. Record the reason and application confirmation before updating the stock record. Otherwise a later reorder may inherit an unreviewed substitute as though it were the original approved configuration.
This guide is not a redesign of the fuel system. It does not approve a different filtration stage, reroute fuel or coolant lines, establish heater performance in a particular climate, or diagnose a water-in-fuel warning. The fuel-water separator guide addresses separation, sensing and service questions; those should not be answered by a supplier shortlist.
It also does not repeat cartridge selection within an already approved cover configuration. If the housing is staying on the vehicle and only routine consumables are needed, order the confirmed service references rather than using a complete-assembly comparison to justify replacing more hardware.
For projects comparing different separator architectures, the Donaldson, Racor and PreLine assembly-program comparison covers a different decision. The present shortlist assumes the DAVCO 382 architecture is already the relevant starting point.
No combined selection is established by the table. Identify the required heating and water-detection arrangements separately, then ask the supplier to confirm their approved combination in the offered assembly. A complete response should show which sensor and connection items are supplied. Do not assume that choosing one optional feature automatically supplies or validates another.
Send both references with the assembly identification and installed-connection photographs. Ask whether the difference reflects a supersession, an alternative approved configuration or an identification error. Do not infer signal compatibility from the connector shape or silently change the order to the current page number. Record the explanation before releasing the purchase.
That depends on the approved supplied configuration and installation instructions, not on whether the old heater appears reusable. Ask whether transfer is permitted, which components are involved and what inspection or replacement requirements apply. If the offer relies on transferring an unverified part, it is not yet a complete replacement plan.
Use it to identify questions during sourcing, then build the receiving checklist from the actual confirmed order. The webpage does not specify every included item or the delivered assembly's unique identity. Receiving needs the approved configuration and exclusions so it can distinguish a correct package from a familiar-looking but incomplete one.
A quotation does not establish the cause of the complaint. The workshop should identify the failed or unsuitable component before purchase and follow the applicable diagnostic procedure. The fuel-filter housing diagnosis guide separates housing, priming and sealing investigations. Do not treat ordering the expected chassis version as proof that an unrelated fuel-system fault has been resolved.
To request an Elecdura aftermarket review, use the Request a Quote form below and describe the installed assembly and unresolved configuration questions. State whether only an identified replacement is acceptable or whether a documented alternative may be reviewed. No DAVCO authorization, exact stock or cross-chassis interchangeability is claimed here.
