Is there something wrong here? I have gone thru 4 filters in the last 10,000 miles! Half of the time was pulling a large trailer getting about 10 MPGs and somewhere in the first 2,000 miles I picked up water in the fuel, does it take this long to get rid of all the water? I have run the tank nearly dry 3 or 4 times now to flush it out. I can't figure it out.
