Hello Guys,

I want to replace my coolant overflow tube, the small dia tube that runs on the top of the radiator, connecting the coolant overflow tank and the radiator neck.

I want to replace it with a silicon tube, and wanted to know, what dia tube to buy and from where. Most do sell as a set and i do not want the set cause i do have the other tubes.

Z1 sells silicon tubes but I am not sure what dia to buy. they have two dimensions 1/4 and 5/16 ..please advice which to buy..

Like a colored silicon hose? Is something wrong with a diameter correct black hose you'd get from the autoparts store?
I will check mine tonight if you don't have an answer by then.

update…

My OEM hose on my 2003 touring is 8.8mm ID and 13.1mm OD...
