zed Posted July 1, 2009 Report Share Posted July 1, 2009 05h00 this morning on my way to work, going up a mountain pass, my truck (L18 motor) started miss - firing badly, then stopped. I found both fuel filters blocked. Thing is, they are both only about 600 miles old. Usually I replace them every 10 000 miles. Never had one blockage before. I run two GUD disposable plastic filters between tank and carb. How long should a fuel filter last? Quote Link to comment
