How do I confirm compatibility before buying?

Check your truck’s current sensor part number and cross-reference the OE numbers listed to ensure compatibility. If your vehicle uses any of the stated references (904-462, 68197868AA, 68197868AB), this Shibeiparts unit is intended as a replacement; when in doubt, consult your service manual or a trusted technician.

• Compare existing sensor part number with the listed OE numbers
• Confirm model year and 6.7L engine match (2013–2018)
• Ask a shop to verify fitment for modified or non-stock fuel systems
