84C603708G2 by the Numbers
Verified identity and fitment data for the complete diesel fuel injector, supplied new for the GE 12V250 locomotive engine.
Every item in this listing is a complete diesel fuel injector of the electronically controlled kind: one sealed body rather than a bare tip or a service kit, built to the Bosch F00BL0J050 reference design, which is why the family carries the Bosch reference label. The 12V250 fuel injector described here meters its own cylinder — the ECU times each injection event, the plunger stage pressurises the fuel inside the body, and the multi-orifice tip atomises it into the combustion chamber — so the assembly behaves as a locomotive fuel injector on the bench and in the engine alike. Buyers reach it by several routes: some search a heavy duty diesel injector by the number on an old depot label, some bring the 323X1003-1 drawing reference off a parts book, and most simply read the code off the body. On the OEM exchange channel a depot hands back the spent unit before a replacement is released, and any fuel injector core charge is settled on that return — the assembly described here is bought outright, with nothing to send back and no exchange account to hold.

Most buyers arrive with a single number alone, so the whole application sits on one page. Send the nameplate 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. Drawing references seen across independent sources: 323X1003-1 / 323X1003 / F00BL0J050.
Fitment verification
- Engine code plate — the plate on the block must read the 12V250 / GEVO-12 build, not another Evolution series rating.
- Old injector identity — the number is read straight off the body or the depot label so we match the unit, not just the engine.
- Tip and seat photo — the multi-orifice tip and the copper seat washer show which build revision the injector belongs to.
About the 84C603708G2 Injector
What an injector of this class does, how the numbering works, and where the unit sits in the GE 12V250 fuel system.
What is a fuel injector?
A fuel injector is the metering and atomising stage of a diesel engine: it takes pressurised fuel and delivers a precisely timed, finely atomised spray into the combustion chamber. The 84C603708G2 covers a complete injector of that kind in the heavy locomotive class: one sealed body holding the plunger stage, the solenoid-driven metering valve and the multi-orifice tip, so nothing is left for the engine to meter separately.
How does a diesel injector work?
The engine ECU energises the solenoid, the metering valve opens at the chosen moment, and pressurised fuel leaves through the multi-orifice tip as a cone of fine spray. On a GE 12V250 there are twelve of these units, one per cylinder, and the ECU trims each individually. A tired injector shows weak delivery or a dribbling tip long before the engine becomes impossible to start.
Locomotive injector explained
Rail diesels run injectors at a duty level road engines never see: long holds at high load, long idles, and fuel quality that varies from country to country. That duty profile is why the locomotive injector is built around a sealed heavy body, a renewable copper seat washer and a tip that keeps its spray pattern over tens of thousands of service hours.
GE injector number explained
The 84C603708G2 number is the parts-book identity for this injector in GE documentation; the same physical unit appears across the drawing set as 323X1003-1 and 323X1003. The numbers name the same part in different documents — a parts-book code and drawing references travelling side by side. We print them exactly as the sources show them and do not expand the coding scheme behind them.
Injector service replacement explained
Replacement is a per-cylinder decision, not a set-change ritual: the workshop identifies the weak cylinder, renews the seat washer, fits the new injector and re-balances the cylinder on the next start. This listing describes the outright route — a new injector bought and kept, no exchange core to return, and the same numbers used to confirm the match. Buyers who run an exchange pool use the numbers here to identify their old unit; buyers who want to own the replacement outright order it directly from this page.
Inside this assembly the tip is integral, which is why no separate internal component number is published for this part number. The unit is built to the Bosch F00BL0J050 reference design, carries a 12-month warranty, and is supplied new under the Vidishi Auto brand as a compatible replacement.

Identification: part number location
The 84C603708G2 code travels on the depot label and the shipment paperwork, the drawing references 323X1003-1 and 323X1003 travel on the drawing set, and the Bosch-side F00BL0J050 appears in catalogue cross-listings. Reading the old body against these lines is the quickest way to settle a match before ordering.
Reference figures come from the 84C603708G2 parts-book record together with the locomotive-side 323X1003-1 and 323X1003 drawing evidence and the Bosch-side F00BL0J050 catalogue listing. Injection pressure, flow and response values are quoted only after a bench test, so they are left as not published rather than borrowed from another family member. Net weight is left as not published because no source ties a figure to this part number, so only the packaged shipping weight of 3.0 kg is stated. This assembly is a complete sealed injector, so no internal component of it carries a number we can bind to the listing, and none is printed here.
Cross-Reference & Interchanges
Need an 84C603708G2 cross reference or an 84C603708G2 equivalent? The numbers below are the ones buyers match against. All are reference interchanges only.
These references are printed so the right injector can be matched, not to claim an origin. The parts-book number and the drawing numbers identify the same physical injector across the documentation set, while the Bosch catalogue number identifies the reference design the unit is built to. We list only the numbers we can corroborate across independent sources. The internal metering valve, plunger and tip 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 body photo and we confirm the interchange set against your build on the same RFQ.
Key Features
Why this injector is built for locomotive service, and what the outright identity means for the way you buy it.
Complete injector assembly
What you receive is the whole sealed body — a complete injector, not a bare tip, a valve or a service kit.
No core return injector
Bought outright and kept: nothing to hand back, no depot core account to open and no exchange paperwork to track.
Injector exchange alternative
A practical route for buyers who cannot wait on an exchange pool: identify the old unit by its number, order the new one outright.
One run injector supply
Bulk programmes are drawn from one production run so per-cylinder output stays consistent across a V12.
Multi-orifice injector tip
The tip carries its multi-orifice hole pattern as photographed, sized for the GEVO-12 combustion chamber rather than adapted from a road engine.
Electronically controlled metering
The ECU times each injection event and trims every cylinder individually, so a fresh unit slots into a balanced engine.
No invented numbers
Where a value is not published against this part number — pressure, flow, coil resistance — 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
Diesel injector symptoms to watch for on a GE 12V250, and the checks that separate a tired unit from a healthy one.
| Symptom | What it usually means |
|---|---|
| Diesel injector symptoms | A weak or dribbling unit drops combustion quality on one cylinder and shows up first as uneven exhaust temperature. |
| 12V250 injector low power | Delivery falling below the class figure on one or more cylinders pulls the whole engine rating down under load. |
| 12V250 injector hard starting | Weak cranking delivery or a leaking seat washer delays the first firing on a cold bank. |
| GEVO engine smoke injector | Poor atomisation from a worn tip raises exhaust opacity on a GEVO rated build. |
| Diesel injector rough running | Uneven delivery between cylinders shows as a lope or beat at idle and light load. |
| Injector cylinder imbalance | One unit drifting out of step with its neighbours changes exhaust temperature spread and fuel burn. |
| Injector diagnostic trouble code | An ECU cylinder-balance or circuit code points at one cylinder for a bench check. |
| Injector return flow test | A return-flow reading taken cylinder to cylinder separates a tired unit from a healthy one. |
Two measurements do most of the work: a return-flow reading taken across the banks, 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 injector alone — contamination past the filter, a worn seat face and long service hours all repeat the same damage, so fix the cause as well as the unit.
How to replace fuel injector on a GE 12V250
A bench-side walk-through of fitting for the 84C603708G2, from a single-cylinder change a depot can do in the shed to a full balance check.
Confirm the number
Match the parts-book number 84C603708G2, the drawing references 323X1003-1 and 323X1003, and the engine plate before a spanner moves.
Isolate the fuel and the battery
Shut off the fuel supply, relieve pressure in the supply line and isolate the battery before opening the high-pressure connections.
GEVO-12 injector removal
Release the fuel line and the clamp on the GEVO-12 build, draw the old unit straight out, and keep the bore covered while it is out.
Injector seat preparation
Clean the seat bore, check the seat face for scoring or carbon, and confirm the bore is dry before the new unit goes in.
Injector sealing washer renewal
Fit a fresh washer every time; the injector copper washer is a one-shot item and reusing it is the fastest route to a blow-by.
12V250 injector replacement
Offer the new unit in square, seat the clamp evenly, and start the fuel line threads by hand before the final pull-up.
Injector installation torque
Tighten the clamp and the line to the torque figures given in the engine manual, working in the sequence the manual sets.
Bleed and first start
Prime the fuel system, crank without firing until the air is gone, then check for weeping at every joint.
Per-cylinder balancing
After the first start, run a balance check on the exhaust temperatures and trim as the ECU allows before sending the unit back into service.
Fit a fresh sealing washer every time, work to the torque figures, and prime before the first start. The seat and the clamp load are the two steps workshops most often rush. A single-cylinder change on a 12V250 uses the same procedure as a full set — change the weak unit, not all twelve.

Buyer Feedback
Field notes from depots and fleets running the 84C603708G2 on GE 12V250 power.
Matched the number on our depot labels against the listing and the drawing references lined up; even exhaust temperatures after a cylinder-balance check. A new outright part with nothing to send back — exactly what we needed.
One cylinder had been lope-ing for weeks and the return-flow check pointed at No. 7. New unit in with a fresh copper washer and the balance cleared. Fast RFQ turnaround and the box arrived intact.
