Sites,
I recall yours and other post's concerning the fuel hose issue. It was one of the first inspections I did when the I got MH. Both filler hoses looked good and I have been able to fuel with out any problems. I hope your dealer/Ford get it right this time. As far as the water pump goes, I'm 100% sure that water was in and around the pump and the pump filter (cracked housing)through the winter months while the MH was at the dealership ( they said it was winterized). I replaced the filter myself after testing the FW system out for the first time when I saw water pouring out of the filter. Dried everything and waited a bit. All OK. I went on to something else, about 20 minutes later, DW started hollering that there is water on the bedroom floor. :h Started looking again and found a slow leak on the bottom side of the pump. The dealer did replace the pump at no charge.
Hope you get yours back in top shape.
