It is possible to buy another “strainer” only if you measure dimensions of the old one and use a reputable brand from Amazon as i would not trust china parts on a Hyosung motor that is already annoyed. As you said, the pump is expensive indeed, you will want to remove the strainer very carefully and replace any “retainer” pins holding it in. As long as the strainger port is the same that can slot in to the pump and isn’t too big (will hit metal wall of tank if it is too big or sticking out too much)
Inline fuel filters can burst eventually, so most of them are china made (very very mass produced in china) for many carb bikes that have very low fuel pressure as the carbs have a tap that is like opening the sink a tiny bit. The electric pumps can push 5 bars of pressure sometimes in a motorcycles , that is some difference! (Hence pressure regulators/manager on your fuel pump, as it is instant on/off on ecu demand)
I will further research if it possible to steal OEM filters from cars using electric pumps (ie. small cars) and get OEM versions. Ie, retrofit OEM Toyota filter gauze (since it’s japanese made i am sure) , and clamp it to hyosung pump , i expect the filter to do its job well since car will have big injectors.
We have to be careful also, as if the gauze is too “open” , it will allow small particles to escape and our small bike injectors will not like it, so we need the gauze to be “extra fine” (or have small pores enough to let liquid through but keep any micro particles trapped inside)
It looks like yours is due for service, so it is a good job you took it out!
