The law essentially says a gasoline tank cannot withdraw fuel from a connection below the fuel level.49 CFR 393.67 (c) wrote:
5. Fuel withdrawal fittings. Except for diesel fuel tanks, the fittings through which fuel is withdrawn from a fuel tank must be located above the normal level of fuel in the tank when the tank is full.
I take this to mean an in-bed auxiliary tank with top connections can pump or siphon to a vehicle main tank without issue.

The law is you cannot have a gasoline aux tank that gravity feeds into another gas tank (ie: feeding into the truck's main factory gas tank). It's legal to do this with diesel, NOT with gasoline.
Is that the law? I thought you weren't allowed to gravity feed to the engine. But I've been wrong before.
There are lots of stationary use engines that use gravity feed tanks instead of a fuel pump, such as generators, lawn mowers, air compressors, water pumps, etc.
