Works great!
Good stuff! There’s no easier or more cost affective way to convert a 3/8” hard line into braided line than this. I used one of these to convert the feed line out of my fuel sending unit into a 6an line. Worked perfectly, was easy to install, looks great and seals up tight. Love it!

99 Ranger fuel line repair
Broke the braided line going to my fuel filter on my 99 ranger. I used a tube cutter on the steel line and used a compression fitting to start my repair. I made my braided line and had a 5/16 fuel filter fitting going to my filter. Worked great and worked the first time. Biggest part is getting that first compression fitting to secure good. Great kit for braided line repairs.
