Diesel Line

Diesel Line Installation Instructions:

Premium Viton Diesel Return Lines

1.) Remove the old injector return lines.  Care is required to avoid scratching the return line nipples.  Use only plastic tools to assist in removal!  Any scratches, gouges, or other damage to the nipples can result in fuel leaks after installation.  Wipe away any grime or residue with a clean, lint free cloth.

2.) When installing the new lines, carefully press the line ends directly onto the injector nipples.

3.) Press the end plug fully into one end of the short section of hose (until it is even with the end) before installing the other end on the last injector nipple.

4.) Install clamps, if appropriate for your engine.
