Refueling
Background - used to have a dually with a diesel transfer tank and now own a gas HD truck. I don't want another transfer tank and not not sure how to refuel now that I can't go through the truck stop ...

You cannot use a gravity feed, the gasoline must be pumped...but it can be pumped to the filler neck of the OEM tank. Here's what I found:
"The Installer/Purchaser is responsible for acquiring fuel hoses,clamps, and an electric fuel pump to complete the installation. The gasoline auxiliary tank connects into the factory fuel system through the filler neck hose. The gasoline auxiliary tanks install similarly to the diesel ones, however, it is not legal to gravity feed out of the bottom of the auxiliary tank with gasoline. By law, the fuel must be pulled from a fitting on top of the auxiliary tank. ATI adds a pickup tube to the gas auxiliary tanks with a hose barb on the top of the tank. You must use a pump, a low volume universal fuel pump, for example, an Airtex E84070 with an on/off switch in the cab, to pull the fuel from the aux tank and pump it into the factory tank via the truck's factory filler neck hose. ATI offers the 1" ( FNA1.0 ) filler neck adapters which work with most gas trucks. These adapters have two 3/8" hose barbs; one where your fuel comes in and one where we recommend running a return line back to the auxiliary tank. On most trucks, you will also need to run another hose from the vent on the auxiliary fuel tank and "T" into the factory installed vent line that runs along with the filler neck hose. This will close the system to ensure you don't get check engine or loose gas cap SES warning lights."
Definitely a bit more convoluted than a diesel auxiliary tank. More hoops to jump through, and a bit more expensive, due to safety regulations.
