Toyota Tundra Flex Fuel Pump Replacement 38 Gallon Tank - Updated Part# 77020-0C170 

This is a 2016 Tundra with the 38 gallon tank and Flex Fuel Pump. The symptoms were hesitation and a feeling of misfires at low rpms under load and horrible gas mileage around 10mpg. The truck started and idled fine and had no check engine lights. After replacement everything is as smooth as the day I purchased the truck and I also had 15.2mpg on the first 140 mile round trip.
