COMPLETE MANUFACTURER REFERENCE / 1 FAMILIES
Give an unusual model the right introduction.
A Weifu WB7 request should begin with the exact pump mark, complete equipment identification and a description of what the unit is doing. When parts lists are hard to find, precise documentation gives a specialist the best chance to identify a sensible next step.
Have a pump identification plate, an engine model or a photograph? You have enough to start the conversation. We will help review the information and discuss available service or parts options for the exact component, without assuming every model is serviceable.
Make a better decision before ordering parts
First, photograph the entire component and any information plate. Then record the engine make, model and serial number, plus the equipment it powers. A pump that looks similar is not automatically calibrated or fitted the same way.
Second, write down the complaint in ordinary language: no-start, difficult starting, intermittent loss of power, a fuel leak, contamination, or a concern discovered during another repair. Include what a qualified technician has already checked. That context can prevent an unnecessary component purchase.
Third, contact DCT before sending a component. Our team will review the information, confirm whether an appropriate service or parts path is available and provide receiving instructions for any approved shipment.
Family-by-family guidance
These are all the pump families named under WEIFU in DCT’s source register. Each note focuses on getting the component identified, separating a symptom from a diagnosis, and making the next step simpler. A family being listed is not a promise of available inventory, parts interchange or repair acceptance.
WEIFU / PUMP FAMILY
WB7
When you cannot find your pump in a typical online catalog, you have not reached a dead end; you have reached the point where identification matters most.
WB7 appears under Weifu in the supplied pump-family register. Because this is a specialized identifier, the right first step is to capture the exact label, engine and any installation history rather than promise a generic rebuild kit.
The family name is a useful signpost, not a complete technical specification. On less-common systems, a wrong assumption can create more downtime than the original fuel complaint.
Before you remove, replace or ship it: Send the clearest photo of the complete pump, every visible number, the engine/equipment serial and a short description of symptoms before discussing parts or shipping.

Before you decide it needs a pump
This reference often appears in older or specialist equipment where an exact number is more valuable than a broad internet search. Model-family naming alone is not a reliable service specification.
When specialized diesel applications where catalog naming can be inconsistent has to earn its keep, the first good result is a reliable identity for the WB7 unit. That saves time chasing an attractive but potentially incompatible replacement.
Identify this WEIFU family confidently
Because “WB7” is a short designation, include the WEIFU maker name in searches and keep the entire identification plate in any inquiry. A short letter code is easily mistaken for unrelated equipment terminology.
When the record is hard to find: For specialized diesel applications where catalog naming can be inconsistent, manuals, old component tags and equipment records may use different numbering. Keep the source of each number in the inquiry rather than silently combining uncertain identifiers.
The observations that help the most
- Take a sharp close-up of all numbers and a wider photograph showing the complete housing, drive and controls.
- Record the equipment make, engine model and serial, plus any manual or historical parts-book number.
- Describe the complaint, storage history and any previous modifications or substituted parts.
Safety and accuracy: Avoid ordering a similarly named pump or assuming service acceptance until the exact assembly has been identified.
Three questions worth asking before authorizing work
- Is the identification from the original plate or an old parts invoice?
- Has the pump been replaced, rebuilt or re-tagged previously?
- Which engine number can be used to verify the correct configuration?
From concern to a practical next step
Start with what the operator noticed, add the facts an independent shop has already measured, and photograph the full unit plus every number. DCT can then discuss whether identification help, additional engine-level testing, a supported component evaluation or a parts inquiry is the appropriate next conversation. The exact work and receiving location are confirmed before anything is shipped.

Your pump is not just a model number.
Tell us what it came from, how it has been acting, and any numbers you can read. Our specialists can review that information, discuss the next step for eligible components and provide the correct shipping destination before you send anything.
