Misfuel risk High
UK D-Max is diesel-only — petrol misfuel at forecourts is a frequent insurance claim on pickups and vans.
If the engine was not started
Do not start — petrol will damage HP pump quickly.
If the engine was started
Replace pump, rails, injectors as required after contamination — follow Isuzu bulletin scope.
Access procedure
- Disconnect battery; remove pump relay and crank to depressurise (D-Max).
- Access pump under rear seat on D-Max/MU-X or use tank drop on trucks as per workshop manual.
- Drain tank, flush if needed, replace filters after contamination.
- Prime diesel system; bleed air on commercial models before restart.
Notes
- Euro 6 AdBlue filler is separate from diesel.
