Flush Bed Fill: Standard bed fill tank with cap. The standard bed fill tank will come with a threaded cap and neck as shown in the pictures which sticks up approx. 3” and sits just below the bed floor. This will require you to have a bed fuel door.

Fuel Level Sensor: We recommend one of three sending units to fit your needs; A 0-90 OHM fuel level sensor for aftermarket gauges, a 75-10 or 240-33 fuel level sensor if you are using stock gauges with our Coyote Swap tanks. 

Rollover Safety Vent: We also include the rollover safety vent, which is a simple ball check valve that allows air in and out of the tank as needed. In the event of a rollover, the ball will drop and block the vent port from leaking fuel. Additionally, it also has a small float inside that will help reduce the amount of liquid entering the vent hose from fuel slosh during normal everyday use.
