Only 4500 miles!!!
A genunie Delco filter plugged up that quick in the middle of summer - so I know its not full of ice crystals from water in fuel... That must have been one crappy tankful, last tank was purchased in Moorhead, MN just off I94. Maybe some rancid bio-diesel blend, or a crusty underground tank?
Just my luck. 99K mile on the odometer, and I'll probably hang an injector next...just out of warranty.
