Product Details
184A215237P5 by the Numbers
Verified identity and fitment data for the complete diesel pump, supplied new for the GE 12V250 locomotive engine.
Every item in this listing is a complete electronically controlled unit pump: one sealed body holding the solenoid head, the plunger and return spring and the roller tappet, built to the Bosch F00BL0P047 reference design. As a locomotive EUP it works in the cam-driven sense — the roller tappet rides the engine cam, the plunger pressurises fuel inside the element, and the solenoid valve meters the delivery — which is why depots order it as a GEVO-12 unit pump for the twelve-cylinder Evolution build. The outright unit pump terms matter as much as the hardware: this is a new unit pump bought and kept, not a rebuilt unit swapped against a returned core. Depot paperwork for the same family also reads like a 12V250 fuel injection pump line item, with the plate-marked 322X1021 above the serial on the identity plates of the photographed units.

Most buyers arrive with a single number alone, so the whole platform sits on one page. Send the identity plate and we confirm the GE 12V250 fitment before you order; the same reference doubles as a depot guide for units coming off a twelve-cylinder locomotive. Interchange numbers seen across independent sources: F00BL0P047 / 332X1021 / 84E901259G5.
Fitment verification
- Engine code plate — the plate on the block must read the 12V250 / GEVO-12 build, not another Evolution series rating.
- Old pump identity plate — the number and the serial line are read straight off the body so we match the unit, not just the engine.
- Flange and connector photo — the mounting face and the solenoid connector show which build revision the assembly belongs to.
About the 184A215237P5 Assembly
What an outright purchase covers, how the solenoid meters fuel, and where the assembly sits in the GE 12V250 fuel path.
What is an outright unit pump?
Outright terms mean the assembly is bought new and kept: the price covers the pump itself, nothing is handed back and no core account is opened. It contrasts with the OEM exchange cycle, where a rebuilt unit is released only after the spent element goes back for inspection and any shortfall is charged. Workshops that want a predictable channel order outright; the interchange numbers stay the same either way.
How does an EUP meter fuel?
The engine camshaft lifts the roller tappet, the plunger pressurises the fuel trapped in the element, and the solenoid valve opens at the moment the ECU chooses so the pressurised fuel leaves through the high-pressure line instead of spilling back. On a GE 12V250 there are twelve of these elements, one per cylinder, and the ECU trims each individually. A tired element shows a weak delivery long before the engine becomes impossible to start.
What is a pump line nozzle system?
The name describes the hardware chain of this injection layout: a pumping element mounted at the block, a short high-pressure line, and the nozzle holder assembly on the cylinder head. The unit described on this page is the pumping element of that chain — it makes the pressure and the timing, while the nozzle holder at the far end of the line turns pressure into spray. The two parts are matched as a system but carried as separate components in the parts book.
Why does a diesel engine need one pump per cylinder?
Because pressure and timing are cylinder-specific. A shared gallery dilutes both: every cylinder receives the same average instead of its own metered shot. With one element per cylinder, the cam sets the pumping stroke and the solenoid sets the spill point, so delivery can be trimmed cylinder by cylinder. That is what keeps exhaust temperatures even across a twelve-cylinder bank.
What does the 184A215237P5 number identify?
It identifies the listing form of this pump family in its GE material-number writing form. The same core string travels as the trade shorthand 84A215237P5, and the identity plates of the photographed units read EUP, F00B.L0P.047 and 322X1021 above the serial line — read at three-times magnification on all three plates. The Bosch catalogue and GE drawing numbers identify the same physical element across parts books.
The assembly ships complete with its solenoid head, plunger and return spring, roller tappet and cast mounting flange integral, which is why no separate internal component number is published for this part number. It is built to the Bosch F00BL0P047 reference design, carries a 12-month warranty, and is supplied new under the Vidishi Auto brand as a compatible replacement.

Identification: reading the plate
The unit pump data plate sits on the solenoid cover: the photographed units read EUP, the dotted Bosch line F00B.L0P.047 and the plate-marked number 322X1021, with the serial line beneath. The listing identity travels on the shipment paperwork, and the mounting flange with its connector confirms the build revision. Reading that plate against these lines is the quickest way to settle a match before ordering.
Reference figures come from the trade documentation of the 184A215237P5 family together with the first-hand plate evidence of the photographed units; the interchange numbers are document-level values, not claims of origin. Net weight is left as not published because no source ties a figure to this part number, so only the packaged shipping weight of 7.0 kg is stated. Flow rate, coil resistance and any pressure value are quoted only after a bench test. No internal component of the assembly carries a number we can bind to the listing, and none is printed here.
Cross-Reference & Interchanges
Need a 184A215237P5 cross reference or a 184A215237P5 equivalent? The numbers below are the ones buyers match against. All are reference interchanges only.
These references are printed so the right pump can be matched, not to claim an origin. The Bosch catalogue number and the GE drawing and service numbers identify the same physical element across parts books, the plate-marked number travels on the identity plates of the units themselves, and the shorthand form appears on trade paperwork for the family. We list only the numbers we can corroborate across independent sources. The internal control valve, plunger and delivery elements of this assembly carry no number that any independent source binds to the listing, so we state none at all rather than a borrowed one. Send the plate photo and we confirm the interchange set against your build on the same RFQ.
Key Features
Why this assembly is built for locomotive service, and what the outright identity means for the way you buy it.
Factory new unit pump
Supplied factory new from a single production run, never rebuilt, never bench-swapped — the condition on the packing list reads New because it is.
Solenoid metered unit pump
Delivery timing is set electronically by the solenoid valve under ECU control, so each cylinder’s shot is trimmed individually rather than averaged.
Roller tappet unit pump
The cam-driven roller follower takes the pumping stroke straight off the engine camshaft — no separate drive to maintain.
Pump line nozzle system
The element pressurises fuel and sends it down a short high-pressure line to the engine’s nozzle holder assembly — a matched hardware chain, carried as separate parts-book items.
Per cylinder unit pump
One sealed element per cylinder on the twelve-cylinder GEVO-12 build, so a single worn cylinder can be corrected without touching the rest of the set.
Complete assembly, not a part
What you receive is the whole pump — solenoid head, plunger and return spring, roller tappet and cast mounting flange integral.
No invented numbers
Where an internal number is not published against this revision, we say so rather than filling the gap.
New and warranted
Supplied new with a 12-month warranty against manufacturing defects, handled against the batch number.
Failure Symptoms
What a tired element looks like on a GE 12V250, and the checks that separate a worn pump from a healthy one.
| Symptom | What it usually means |
|---|---|
| Bad EUP symptoms | A weak or seeping element drops combustion quality on one cylinder and shows up first as uneven exhaust temperature. |
| GEVO-12 engine misfire | A cylinder losing its metered shot lopes at idle and misfires under light load before the fault is obvious at power. |
| Locomotive engine power loss | Delivery falling below class on one or more elements pulls the whole engine rating down under load. |
| Locomotive diesel hard starting | Low cranking delivery on one element or a leaking spill seat delays the first firing of the day. |
| EUP solenoid failure symptoms | A solenoid that will not command leaves its cylinder dead or untrimmed — the ECU usually flags it first. |
| EUP fuel leak | Weeping at the high-pressure line connection or the element seat costs delivery and shows as a wet flange. |
| Locomotive engine rough idle | Uneven delivery between elements shows as a lope or beat at idle and light load. |
| When to replace a unit pump | When a return-flow or bench reading on one element drifts out of class with its neighbours, change the element — not the whole set. |
Two measurements do most of the work: a return-flow reading element against element, and a bench spray and seat-leak check. Recognising these signs early keeps a unit out of a line failure. The root cause is rarely the pump alone — contamination past the filter, a worn tappet face and long service hours all repeat the same damage, so fix the cause as well as the assembly.
Fitting the 184A215237P5 on a GE 12V250
A bench-side EUP installation guide for the 184A215237P5, from a single-element change a depot can do in the shed to a full first-start check.
Confirm the code
The unit pump pre-installation check starts here: match the listing identity 184A215237P5, the plate-marked 322X1021 on the old body and the engine plate before a spanner moves.
Isolate the fuel and the battery
Shut off the fuel supply, relieve pressure in the high-pressure line and isolate the battery before opening any connection.
Unit pump removal on the GEVO-12 build
Unbolt the old assembly on the GEVO-12 build, note the flange orientation, and check the tappet bore and the mounting face for scoring or debris — a roller tappet inspection while the bore is open costs nothing.
12V250 pump change procedure
GEVO-12 unit pump fitting starts with a fresh sealing washer, a clean flange face and a renewed o-ring — EUP o-ring renewal belongs to every change, not only to overhauls.
Unit pump torque sequence
Seat the assembly to the torque figure given in the engine manual, working evenly across the flange so the element does not go in crooked.
Check the flange and connector
Confirm the bolt pattern and the solenoid connector keyway against the old body before you commit to the change.
Prime the fuel system
Bleed the supply line and crank without firing until the element is fully bled, then check for weeping at every joint.
First start and balance check
After the first start, compare exhaust temperatures cylinder to cylinder and trim as the ECU allows before sending the unit back into service.
Fit a fresh sealing washer every time, work to the torque figure, and prime before the first start. The seal and the timing position are the two steps workshops most often rush. A single-element change on a 12V250 uses the same procedure as a full set — change the worn element, not all twelve.
Warranty & Support
Every 184A215237P5 assembly is covered against manufacturing defects, handled against the batch number on the box.
Because the assembly is bought outright, the cover is simple: manufacturing defects are handled from the ship date against the batch number recorded on the box.
Every assembly ships with these terms in writing on the packing list that travels with the consignment.
Twelve months against manufacturing defects — the same cover on a single element as on a full-set programme.
Contaminated fuel, water in the system, incorrect fitting, or a root fault elsewhere in the fuel system.

Buyer Feedback
Field notes from depots and fleets running this pump family on GE 12V250 power.
Matched the listing number on our depot paperwork and the plate-marked number on the old units; even exhaust temperatures after a first-start balance check. A new outright part with nothing to send back — exactly what we needed.
One element replaced a tired pump on a twelve-cylinder unit; hard start cleared and smoke dropped. Fast RFQ turnaround and the carton arrived intact.
