I can assure you either position can blow the motor. Its a horizontal shaft in the Glowworm.
A small leak in a horizontal one has a better chance of leaking out rather than getting into the motor.
The vertical orientation allows the gland but to fill up halfway to the level of the fixing clip hole.
