piling the mileage on...
The best bet is to use some kind of filter if possible when filling the tank.
My thoughts are intended to provide a sounding board for your own.
Some of what I say may go against your own thoughts and may seem harsh, targeted and malicious.
This is not my intention – I am simply using my experience, including other peoples, as a way of debating and giving advice - of which there is no guarantee that it's correct
That is crazy! I agree with Colvert, find some type of material / filter to use when filling. Anything will be helpful compared to that! Wow.
