Sourcing Guide
The three adjacent OTX fuel-filter-assembly codes show different complete-unit layouts. Compare the housing, primer, bowls, mounting bridge and recorded references before ordering.
Three fuel-filter assemblies appear next to each other in the OTX catalog, but their photographs show three different complete-unit layouts. TF 0214ZC-01 is a compact dark housing; TF 0215ZC-01 is a single-bowl unit described as a pump assembly; TF 0216ZC-01 has two bowls under a common mounting head. They should be treated as separate enquiries, even when a buyer's request only says “diesel filter assembly.”
The product-family listing groups these three catalog codes for sourcing. The grouping does not establish that one can replace another. The old assembly, its mounting position and every fuel-line connection still need to be checked against the proposed item.
| Catalog code | Recorded reference or wording | Visible complete-unit layout | Recorded thread clue |
|---|---|---|---|
| TF 0214ZC-01 | FH21219 | Compact dark cylindrical housing with cap and side fittings | None printed in this catalog block |
| TF 0215ZC-01 | R120-10MB-AQII; catalog wording “pump assembly” | One filter bowl below a metal head with front-facing ports | M12 × 1.5 appears twice, without labelled measurement positions |
| TF 0216ZC-01 | C0810A-0000; C0810B-0000 | Two filter bowls below one shared metal mounting head | M14 × 1.5 appears twice, without labelled measurement positions |
Source: OTX filter catalog, page 76, third row. The references and thread marks above are transcription of that catalog block, supported by a visual check of the individual images. The catalog does not say which physical connection corresponds to each repeated thread mark. Confirm port positions and measurements on a drawing or sample before treating the marks as installation specifications.
A replacement filter element or spin-on bowl is a different purchase from the mounting head, housing and fittings together. Before quoting, state whether the request is for the complete assembly, one service bowl, a housing or a separately supplied accessory. A photograph of the installed unit should show the entire assembly from mounting bracket to the lowest drain or bowl, including the fuel-line connections.
For TF 0216ZC-01, the source photograph shows two bowls under one head. “Two filters” on a parts list could mean two separate service elements, or one twin-bowl complete assembly. Write the supply scope explicitly so the purchase line and quotation describe the same object.
For the compact TF 0214ZC-01, compare the cap, overall housing silhouette, side fittings and lower features with the removed assembly. The catalog records FH21219 but does not give a mounting pattern or connection thread in this block. A matching reference alone cannot fill those gaps.
For TF 0215ZC-01, photograph the whole metal head, the visible port faces, mounting bracket, lower bowl and any pump control. The catalog calls this a pump assembly and records R120-10MB-AQII. If a replacement is offered with a similar bowl but a different head or primer arrangement, ask for a dimensional drawing and port map before approving it.
For TF 0216ZC-01, record the twin-bowl spacing, the common head, upper mounting points and the position of each fuel connection. Keep both catalog references, C0810A-0000 and C0810B-0000, with the enquiry until the supplier establishes which one applies to the actual unit. The catalog image alone does not assign a separate reference to each bowl.
The catalog prints M12 × 1.5 twice for TF 0215ZC-01 and M14 × 1.5 twice for TF 0216ZC-01. This is a useful distinction between the two catalog entries, but the print does not identify the measurement location of either occurrence. Do not mark a specific inlet, outlet or mounting stud from those numbers alone.
When a thread size is critical, photograph each physical port straight-on and from the side, then record a measured size or request a supplier drawing. Also document the fuel-flow direction and hose orientation on the installed unit. Even a correct nominal thread can be unusable if the ports face the wrong way or the bracket does not fit the available space.
For each assembly, send the exact TF catalog code, complete old-unit reference, required quantity, truck and engine identifiers if known, and the supply scope. Add five images: an installed wide view, the whole removed assembly, the head and ports, the mounting face, and the lower bowls or housing. Mark any unreadable reference as unreadable. If several units are being ordered, keep their photographs in separate folders named by vehicle and catalog code.
The three assemblies can travel with other fuel-system maintenance parts in a mixed shipment, but they should remain separate purchase lines. Use the parts enquiry form to send the old-unit photographs and request confirmation of the complete assembly, connection layout and included service parts before quotation.
The cover and inspection image are AI-generated illustrations informed by the catalog photographs. They do not document actual stock, an installation or a fitment test.
Use this guide to organize a clearer quote request instead of choosing from a short product list.
Part number, truck brand, model, engine model, chassis number and old-part photos help confirm the correct replacement before quotation.
Filters, brake parts, clutch parts, chassis parts, cab parts, bearings, sensors and assemblies can be checked together for one practical order.
Share quantity, packing preference and whether the order is for fleet repair, workshop use or distributor stock.
Send part numbers, truck models, chassis numbers, old-part photos or sample photos. We can help check multiple items and combine them into a practical export order.
