I drove the new to us Alpine home this past Sat. I left the dealership and proceeded to fill up as the gauge was on empty. I had to slow the refueling down a lot as the pump would shut off. After making sure the tank was full, I checked the gauge on the dash and it was showing 1/8 below full.
I know the vent tube could be kinked and also the sending unit could be bad.
I will drive the unit more to help empty the tank before taking back to the dealer.
Since this tank is 97 gallons, I think I should be able to go about 800 miles before refueling, based on an average of 8 mpg.
Helpful advice is most appreciated.
