Bend a piece of coat hanger wire to the shape required, take it to GSF, and see if they can match it with anything, your looking for a longer section that can be cut to length, if you find something that fits perfectly, find out what car its for, so people know for future reference...
Also note that any cuts made to a hose, MUST be made on a straight section, and NEVER on a bend, cutting on a bend will reveal a cross section that is not circular, and will never fit properly!
