I would look for a clear vinal hose or something simular so you can see if it's getting pluged up . look for one that UV rated , so the sun does'nt degrade it quickly . JMHO
Make sure your hose has a smooth inner OR the turbulence will reduce the amount of flow to your equipment and cause the pump to work harder and the battery to be used up sooner.
that one takes a 3/4 hose, what else is 3/4? garden hose...
I have gotten the cheep pump hose from Jerrys, home depot, and walmart
this works best as it doesn't collapse or get pinched. Attwood 6' Bilge Hose with Clamp - Walmart.com
