97 L67 nylon fuel line crack by engine

Post by redmetrix »

One of the nylon fuel lines has a crack in it and is leaking fuel. The yellow circle in the picture shows the area where the crack is, it is right where the two lines make a turn and the crack is right in the middle of the turn. It is pretty close to where the lines connect to the fuel rail. Looking for help on the best way to fix this. Can the line be repaired, if so what would I all need? I know another option is replace the entire line from the engine to back of car but I am thinking that may not be necessary.

Dorman makes barbs, unions and repair sections for nylon line. There are some youtube videos of guys doing these repairs.

Dorman also makes push-fit connectors that don't need special tools and boiling water.

Used a 90 degree Dorman push fit connector and also a new piece of nylon line with the connector to the fuel rail on it and it's all fixed now.
