Have a '91 F Super Duty with a 7.3 diesel. Was a former wrecker chassis and have built a 10' flat bed for it. Wanted to install a factory "behind the axle" aux. fuel tank. Found out there isn't enough frame behind the axle to install one - brother thinks the frame may have been shortened for the wrecker body. And the main 19 gallon tank isn't enough fuel capacity. And I don't want an aux. tank mounted on the bed - want to keep it clear...

Been looking at TANKS Inc. gas tanks for street rods, muscle cars, custom cars and trucks website at their universal tanks, with the thoughts of running an "outside the frame" tank. The tank in mind is this one: Universal Steel and Stainless Steel Fuel Tank - U2 Series

My question is if those fuel line fittings on top of the tank are large enough to flow enough fuel?
