Product Details
Sub Fuel Tank Unit ISUZU TFR54
,Fuel Level Sensor 4JA1 4JB1
,OEM Fit Fuel Tank Unit
The Sub Fuel Tank Unit with OEM numbers 8-94318396-0 / 8943183960 is a direct-fit replacement for ISUZU TFR54 and D-MAX pickups equipped with 4JA1 (2.5L) or 4JB1 (2.8L) diesel engines. This unit combines a fuel level sensor with the sub-tank pickup assembly, delivering accurate fuel gauge readings and reliable fuel delivery from the secondary tank.
- OEM Cross-Reference Verified: Replaces 8-94318396-0, 8943183960, and 94318396 — confirmed against ISUZU parts listings.
- Fitment Confirmation: Confirmed for ISUZU TFR54 with 4JA1 / 4JB1 diesel engines; also listed for D-MAX applications.
- Quality Certification: Produced under an ISO/TS16949 quality management system — certified by supplier documentation.
- Pre-Delivery Inspection: Each unit undergoes a float arm movement check and sensor resistance measurement before packing — per in-house QC records (standard: 100% inspection before shipment).
- Fuel gauge reads empty or full regardless of actual fuel level.
- Fuel gauge fluctuates erratically or drops to zero intermittently.
- Low fuel warning light does not illuminate when the tank is low.
- Fuel gauge reads incorrectly only on the sub-tank (main tank reads normally).
- Visible corrosion or fuel residue on the sensor connector.

| ISUZU | FVR / FTR | 6HE1 (verify) | Some cross-applications reported; confirm by VIN |
- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily intended for ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. Both "short" and "long" pushrod variants exist within the MC828264 family.
- Always provide your VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
| QC Item | Verification Method |
|---|---|
| Float arm movement | Manual sweep test — full range verification |
| Sensor resistance | Multimeter measurement at empty / half / full positions |
| Connector pin condition | Visual and fitment check against OEM gauge |
| Housing integrity | Visual inspection for cracks or fuel residue |
- Disconnect the battery negative. Relieve fuel system pressure per the workshop manual.
- Access the sub-tank unit — typically through an access panel under the rear seat or by lowering the tank.
- Disconnect the electrical connector and fuel lines (if equipped with pickup).
- Remove the retaining ring/nuts; withdraw the old unit carefully.
- Install the new unit with a new gasket/seal; tighten the retaining ring to [XX Nm] (consult workshop manual).
- Reconnect the fuel lines and electrical connector.
- Function test: Turn ignition ON (do not start). Observe the fuel gauge reading and compare against the known fuel level. Start the engine and check for leaks.
Avoid running the tank completely dry — the sensor relies on fuel for lubrication and cooling. If gauge readings become erratic, inspect the connector for corrosion before replacing the unit.
- Neutral carton / pallet / wooden case (per supplier standard).
- Suitable for wholesalers, repair shops, and fleet maintenance.
