Fuel Return Line: Description and Operation
Fuel Tank And Mounting
WARNING: To reduce the risk of personal injury, always cover nylon fuel lines with a wet towel using a torch near it. Also, never expose the
vehicle to temperatures higher than 115° C (239° F) for more than one hour, or more than 90° C (194° F) for any extended period.
Take care not to nick or scratch the fuel lines. If damaged, they must be replaced.
FUEL TANK
The fuel tank is used to store fuel for the vehicle. The tank is molded from high density polyethylene, and is located in front of the rear wheels on the left
side of the vehicle. It is held in place by two metal straps attached to the underbody. The tank shape includes a reservoir to maintain a constant supply of
fuel around the fuel pump filter during low fuel conditions and aggressive vehicle maneuvers. A filler neck check-ball tube is installed after the tank is
made, and extends from the tank inlet to the reservoir. The check-ball, located inside the tube, prevents fuel from splashing back out the fuel filler neck
when refueling.
When working on or near the fuel tank, be sure to observe important information molded on the bottom of the tank.
