Review on 4Pcs Fuel Line Connector 800 191 by Seth Singh

This coupler did not work at all. Before connecting the coupler, I took great care to ensure the fuel lines were cut cleanly and evenly. I turned the key without starting the car to prime the fuel pump and gas burst from both ends of the line. I figured it was just a bad clutch so I put a second one in and the same thing happened. Then I settled on a brass compression fitting and it worked. Don't trust them, especially with fuel lines.
