fuel Pump problems

Hi just imported this forester from japan about 2 months ago,

Today my Forestor S/TB 99 failed to start and i eventually had the fuel pump replaced, , as he was fixing the pump he tried to flush the filter and each time the filter ejected a mixture of fuel and soil/clay like particles - basically not just fuel
The mechanic recomended that i also replace the fuel filer which am planning to do

does any one know how soil/clay like particles can end up in the fuel filter, i noticed that the fuel pump had its own filter that should greatly limit the particles going to the filter or is this what the fule filter is supposed to do any way?

IF you or previous owner ran really low on fuel its possible you have sucked up crap from the bottom of the gas tank. Change fuel filter you don't want your injectors to get plugged up, May be good idea to run a good dose of cleaner ,for a few tanks. Don't run your gas tank low if possible.

I think fuel filters are just a paper substrate much like an oil filter, so it's not likely the filter broke down.

Either internal corrosion (unlikely, as long as the car didn't sit for years with no fuel in it), or sucking bad things through the fuel pump sock and eventually accumulating in the fuel filter.

Either way, replace the fuel filter.

You also might want to give blowing the lines out a shot. It's something I've always wanted to try (with brake lines and such), but never got around too. It shouldn't be too hard, and would probably blow anything out that's attached itself to the walls of the hardlines.
