Oil pump line to carb was created by Superdad60

1977 DT400e mono

I searched the forms, looking for the size of the tube that goes from the pump to the carburetor. Inside diameter and outside diameter so it fits through the grommet. Any information appreciated. I like the translucent yellow poly so I can make sure oil’s making its way.

I removed the oil pump cover, and there was a small amount of two-stroke oil in there. I think I may have a cracked line as it’s the original oil line.

thanks

This is still available from Yamaha and I would recommend using it. You may have to cut it to length.
