35mm flex hose for drinking water tank & grey waste

[ElevenSpots]

Putting my van back together and need to replace my 35 mm hose filling the water tank from the outside flap

I can’t get 35 mm flexible hose anywhere - everything I’ve ordered is too ridged (need some for the sink waste water too)

Also -anyone know a solution for the impossible to get “Grey Water Sink Drain Flange w/ Cap “ - so I can connect the waste water pipe to the flange above the floor and the water then flows out of the flange below the van floor?

Thankyou in advance
