Tell us what you have. Tell us what it is doing. We will help you figure out the next practical step. You do not need to speak fluent pump-catalog to start – a clear photo of the identification number is worth a thousand guesses.
Start your service request
Contact name and company (if applicable); phone and email; city and state; manufacturer; complete pump or injector number; engine make, model and serial (if available); equipment and application; symptoms and any error codes; whether contamination was found; work already performed; preferred service: test, clean, repair, rebuild, refurbish, or calibrate; and photos of the full unit, nameplate and connectors.
Include a short note about timing if your equipment is down. Do not treat a request as a confirmed shipping authorization until our team supplies current intake instructions.
What happens next?
We review the information available, clarify identification when needed, and explain whether and how the component can enter our mail-in intake process. We also discuss the applicable repair authorization and return-shipping arrangements.
A real number beats a lucky guess
If the pump tag is worn or missing, send the engine and equipment information and multiple photos. We will explain what more is needed to attempt identification.
What makes an inquiry especially useful
A complete part number is the single most helpful detail, but the story around the part matters too. Describe how the engine behaved before removal: Did it become harder to start over several weeks, stop suddenly during a job, lose power only under load or develop a leak after a long period of storage? Mention any relevant diagnostic codes, recent repairs, water-in-fuel warnings or metallic debris. Those details help distinguish an inspection for a suspected failure from a component that simply needs identification or a known maintenance service.
If the component has already been removed, photographs of the pump from several angles are useful. Include the label or stamped number, drive connection, electrical connector where fitted and fuel-line connections. Never assume that two pumps are identical because they have the same number of outlets or a similar housing. Calibration, mounting and control differences often live in the suffixes of the part number.
What to expect from an initial conversation
We begin by establishing what the component is and what service question needs answering. Some customers want to know whether a pump is economically rebuildable. Others need help identifying the correct replacement specification or investigating an apparent fuel-system failure. The next step may be a discussion of available inspection or bench-testing procedures, clarification of engine-side findings, or instructions for an accepted mail-in evaluation.
There is no need to guess which technical service category to select. Explain the problem in your own words and include the information you already have. If the part is unsuitable for a particular repair process, the appropriate response is to discuss that limitation rather than suggest work that cannot be supported. For the physical packaging process, see how mail-in diesel repair works.
Why we ask customers to contact us before shipping
Diesel injection components vary widely in weight, residual fuel content, electrical sensitivity and packaging needs. Confirming acceptance first reduces the chance of sending an unsupported assembly or having a valuable pump damaged during transport. It also allows the shop to explain the required documentation and the current shipping procedure. Used fuel-system parts must be prepared and shipped according to applicable carrier rules, and the recipient needs enough information to identify the component upon arrival.
