I just got my solar panel from amazon yesterday and hooked it up to its own dedicated pump with some cheap non-cuffed hoses I had from before. They leak just exactly like they used to. Clamping them tighter seems to make them leak faster!
I've tried teflon tape with zero luck. Had a lot better luck with electric tape on the nipple the hose slips over but still slightly leaking on the output of the pump, the inlet of the panel + the outlet of the panel.
On my filter/pump setup I used to use these hoses and hated all the leaks, I bought some cuffed ones from the pool store and that fixed it right up. But I can't spend an extra $40 right now on those if there's a way to make these cheap ones work better short of siliconing them in place.
edit: hoses like these are what I'm trying to make work
