I the spring of 1963, Studebaker changed Avanti windshield washer hose material because......?.....

1) Hoses splitting open.....2) Hoses too short (binding).....3) Hoses staining paint.....or.....4) Hoses loosening on nozzle

Come to think of it, I can understand the windshield washer solvent Studebaker used staining the paint....but it's a little hard for me to grasp how the material the hose was made from could cause paint staining.

Vinyl (PVC) tubing is made flexible by the addition of plasticizers added during fabrication. There's always a chance they can leach out and cause the problems stated.
