You may want to try checking Lowes. The local one here carries them but under a different name and with a blue hose versus clear. I have both the Super Siphon brand and the Lowes one so I compared them and the shaker part is spot on. I use the clear for fuel and the blue for water.
I know I've seen one locally but can't remember where. I have a lowes, pep boys and harbor freight within 3 miles of me so I'll try them if their open tomorrow.
