Even the very best hose eventually will let odor through cause
pvc-softeners have been used to achieve a bend-able hose.

You can solve the odor-problem radically and for just a few bucks by
using rigid pvc-tube. When a part of your installation consists of a
hose going upwards there will allways remain a rest of fluid/solid in
that particular part of the hose. This is the area where the odor will
get through on a given moment (depending on how much softener was used
in the pvc).

My 2 cts: replace the upgoing part of the hose with a piece of rigid
pvc-tube. Better still: replace as much as possible. Using multiple
45 degrees bends will allow you to fabricate a piece of tubing that
will fit, otherwise you can bend a tube by using a heatgun. You can
use small pieces of top quality hose to connect to your head and
tank. The rigid pvc is off course without softeners so it will last a
lifetime and will never let any odor through. And it's a LOT cheaper
than the 5-star hoses that will give in after -at best- a few years.

Hope this helps,
