Fuel injected vehicles have reservoirs inside the fuel tank to maintain fuel near the fuel pick-up during cornering or low-fuel operation. These reservoirs could block siphon hoses or tubes from reaching the bottom of the fuel tank. Repeated attempts, using different hose orientations, can overcome this obstacle.
On Explorer/Mountaineer models, the front fuel tank strap is bolted to the skid plate and will be disconnected when the plate is removed.
On Ranger vehicles, the rear fuel tank strap has two connections which must be unbolted.
