Detailed Product Overview

This Dorman fuel line connector is built for service work where the original connector is cracked, worn, or no longer sealing properly. Instead of replacing the full fuel line assembly, 800-051 lets you repair the damaged connector section and restore the connection point with a direct-fit part. It is a practical OE-style repair for vehicles such as Ford Ranger, Ford F-150, and Mercury Sable applications where the fuel line uses a 5/16 in. quick-disconnect elbow.

This part cross-references Anchor 3068 and Dorman - OE Solutions 905-509 for the same application.
