If there is room/space you could apply 3 Clamps per Hose end.

The advantage is that the Real Crimp Tool for the Oetiker Clamps is around $30 with copies or other makers tools for less or cost more depending on the features you need.

Or you can use a Nail Cutter or Tile Nippper at $5 or less as I did on the Oil Cooler ends of My Oil Cooler Hose to apply the Oetiker Clamps..
