Review on Dorman 800-191 5/16-inch Fuel Line Connector, Pack of 2 for Improved SEO by Matthew Perez

Worked great. Used it to repair a 5/16 fuel line. Easy Installation I have a hard plastic line covered with an outer layer of rubber. I had to remove the outer cover enough to insert the connector. Using a craft knife, carefully remove the outer sleeve, then insert into the inner tube and snap into place, creating a tight seal. I used it on a 1991 F150 fuel return line.
