Well, the pressure washer won't get started real soon. The fuel tank is full of rust particles! Good old Ethanol! Here's some pics. Luckily, this has a filter that screws into the tank and kept it from the carb. Bowl was a little nasty, but cleaned up okay with carb cleaner.
The funnel/filter after draining the tank. It has a fine screen in the bottom.
This was in the funnel.
This filter goes into the fill neck of the tank.
And this is after a short rinse with cider vinegar.
I went a bought a bottle of CLR to see if it help. May end up buying a new tank for it.
