All,
Hello I am a first time user here and am in need of some help. Can anyone tell me the ID of the oil line that runs fron the oil pump to carb boot? Thanks in advance!

 

I think it is just a generic oil line, I have a 1993 Polaris 350L 4x4 similair to the 400L and I had to replace it and used a simple fuel line from The Home Depot. I also wrapped garden fence wire around it to keep it from touching the hot engine. I think to get the oil line off you have to remove the cover on the oil pump and then you can access it.
