Anyone have suggestions for aftermarket fuel pumps? Kemso, QFS fuel pumps?

Been looking at aftermarket fuel pumps, pretty sure there is something wrong with mine, when priming my bike it sounds weird like the pump hose has a small leak in it. Bikes been stalling really bad when trying to ride, stalls in idle...

A new OEM fuel pump is $340 but this KEMSO OEM replacement is only $40 and it looks pretty decent.

Anyone have any suggestions or experience with the KEMSO or QFS pump pumps?
