If the fuel pump moved any of the paraffin to the filter it will need replaced if it just stays in suspension it will go back to normal but once you pack some in a filter it will stay indefinitely. We have had 40+ calls a day about gelled trucks these past two days. Same advice tow it some where warm when the fuel no longer looks like jelly add 911 or howes change the filters and fill with additive as well and hope that there is not any paraffin in the lines
