  • Direct-fit style component for listed GM truck and van applications

Detailed Description

Installation Notes and Tips

Confirm the seal dimensions before installation: 44 mm inner diameter and 3 mm thickness. Inspect the sealing surface for debris, scoring, or distortion, and replace the seal during fuel pump service whenever the original O-ring shows flattening, cracking, or swelling. Verify vehicle application by year, make, and model before ordering Elring 268.550.
