Mysterious tubes??

I've been pouring over the Yamaha parts explosions, and I've found something curious. Both of the Seca II's in my garage are apparently missing some parts, '92 and a '93. Does anyone else have these mysterious tubes?

This drain tube, leading from that nipple on the bottom of the fuel tank by the petcock, it's a drain connecting up by the fuel cap for draining away spillage and water, etc. Yamaha Pt# 90445-105K7-00

This drain, maybe vent tube, connecting to that nipple on the left bottom side of the airbox. Looks like there's some type of inline filter too. Maybe to prevent draining oil from the crankcase breather tube that collects in the airbox from spilling on the ground or maybe to clean air entering the airbox from this tube?
