The outside diameter of the coolent pipes going to the front of the vanagon is 1 and 3/8 inches in diameter.  My adapted 
"cutoff" hose at the other end fits on to a pipe fitting that is 1 and 1/4 inches in diameter.  So I am looking for a straight rubber coolent hose that is about 3 inches long that has an inside diameter of 1 and 3/8 at one end and reduces down to 1 and 1/4 at the other.   

A common plumbing pipe reducer cannot be used because the size increments are by the 1/4 inch in diameter, not by an 1/8 inch. 

I do not think that a 1.25 inch hose can be "stretched" to fit onto the 1 and 3/8 inch pipe, nor is it possible to clamp a 1 and 3/8 hose onto a 1.25 inch pipe without leakage.
Somebody out there must have dealt with this problem, or did everyone cut up their old WBX hoses?
