Misfuel risk Moderate
Gasoline-only in the US. Taller SUV fuel door height can still lead to diesel hose selection errors at combined pumps.
If the engine was not started
Keep ignition off. Drain tank through OEM pump access, replace filter if specified, refill with correct gasoline.
If the engine was started
Running on wrong fuel can damage HPFP and injectors; follow TechAuthority diagnostics and insurer guidance for component replacement.
Access procedure
- Relieve fuel system pressure per OEM service information (disconnect pump fuse/relay or use scan tool as specified).
- Disconnect the negative battery cable.
- Access the fuel pump module per OEM (rear seat service hole, trunk floor, or cargo area—varies by model).
- Disconnect fuel lines and electrical connectors at the pump module using line-specific tools.
- Drain the tank into approved Class 3 containers; bond/ground per OSHA 29 CFR 1910.106.
- Inspect the tank interior; replace in-tank filter if contaminated or per OEM.
- Reinstall the pump module with a new seal; reconnect lines and wiring.
- Refill with the correct fuel grade; prime the system and check for leaks before road test (Alfa Romeo procedure).
Notes
- AWD models: service on level ground to avoid tank sump issues during drain.

Frequently asked questions
Is there a Stelvio diesel in the US?
Alfa Romeo did not sell Stelvio diesel models new in the United States. All US-new Stelvios are gasoline.
Where is the fuel pump on a Stelvio?
TechAuthority typically routes access through the rear load floor under the carpet; exact steps vary by model year.
Can I siphon a Stelvio from the filler neck?
That is not a Stellantis-documented remediation method. USIFDA certified work uses OEM tank access procedures.
