A37 Petcock

A37. 16x1.5 female spigot down

16×1.5 spigot down  N/A
16950-045-005   Off-On only

In most cases, spigot right (above) can substitute for spigot down. The valve can be aimed at any angle, so “right” can become “back”.

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).
