Datsunrides(Mark) writes "I found a replacement for the cowl drain hose (with some direction). Not perfect but darn close. All I had to do was cut the end that connects to the cowl about 1". Judge for yourself. Note: the hose is molded this way. It is not twisted or modified to make the turn.

Most important, the part #!
Hose is a snug fit in the grommet. Had to lube it up a bit.
Old Part # was GOODYEAR M61720 and Kragen/PartsAmerica has it for 11.99.
New Part # is Gates #21895 available at O'Reillys Autoparts(TETREAULT STEVE-3/28/18)
