I agree, get rid of that hose, when the pump is pulling hard, that soft walled hose will kink easily, especially on hot days and we are not even in the hottest part of the year yet.
Get some thick walled hose or the kind with the wire running through it, that clear polybraid collapsed with my rig in the past so I changed it out and went with larger diameter hose so the pump would not cavitate.
I would also get a larger filter screen, that one is kind of small and if you get a good amount of trash in the line, that one will clog up fast. There are the big blue bowl types out there that many guys have gone to, myself included that are basically the same thing but many times larger for more surface to clog up giving you more run time.
There are many threads about this on this forum if you want to see what other guys have rigged up.
