Cleaning a fibreglass tank

I guess you can't remove the tank ?
This was the only way the coins would work... By tumbling them around in the tank.
Turning the tank over and shaking until the coins were out.

Sounds like a big fuel filter is needed...

Thanks for your reply. Once they are in, I don’t know how could get the coins out of the tank.
