Wanted to replace my wiper reservoir tubing and ordered 1/4 x 3/8" tubing from amazon. This tubing is bigger "OD" than existing. I do have an existing Wallloth order I was going to place, so the $5 euro price is not an issue. I am wondering if the Art.-No. A61661357388 is a metric and smaller ID. The 3/8 is a bit big for the existing clips. Figured I would ask before I return the Amazon order.
