Joshofalltrades.... if you worry about small metal shavings collecting on the fuel shutoff solenoid couldn't just be cleaned every so often? Like during an oil change? They don't look that hard to pull off, unless I'm looking at the wrong thing.
Side note with how cold winter has been here, down in the negative temps for highs. I have cut back to a gallon every fill up. I tend to not go bellow a 1/4 before I refuel. Truck seems to not mind it that thin to much but you can smell it burning the oil when it first starts. Till it gets nice and warm.
