Its probably just automotive vacuum hose or something anyways. Just go to Advance and buy a couple feet. You can probably get close to mimicing the fitting by stuffing a screw or bolt in the end of it.
Tried various hoses, stripped wire coverings, etc. and none of them hang straight, they all curl up.
The fitting on the end of the sand hose looks just like the quick-connect ones used on fueling racks, thus that choice.
Tried GI Joe fuel nozzles which are too large to look good.
Was hoping to use the sand hoses, which work just right to look good, hanging down straight, etc.
