I'd rather not spend the $40 for a new weep-hole catch-tank (119.200.03.85) for a M119 water-pump just for the tube that needs replacing.

Mercedes has them in Germany (119.200.00.52) for $15, but it must be just some simple tubing.

Anyone know the specs (e.g., inside-diameter), and the type of material ?

BTW, the current tube is black, made of some type of plastic, that is flexible and heat-resistant.

TIA,
