I honestly do not know. It takes a while (hours). The aux fuel line is pretty small and I also wonder if there is some restriction due to the 1-way valve where it meets the OEM fuel filler hose.
I decided to top off the OEM tank once at home so I opened the aux tank on/off valve and checked the dash gage after an hour - the fuel gage had hardly moved.
But the overnight method works great. I have almost 38 gallons in the stock tank and I get 11 1/2 - 12 mpg so that's about 450 miles towing on the OEM tank. And I don't really intend to go that far in one day. I'm now retired and officially not-in-a-hurry.
I'm in favor of the gravity method; it's nice and simple, no electricity needed. And the RDS tanks do have a simple gage built in that appears to be pretty accurate so you can tell how much is left after refilling.
I don't want this to sound like I'm advertising for RDS. I have no connection to them. Their prices are good and the tank as well as the attachment kit work exactly like they're supposed to. I'm real happy with mine.
One last thing - I read somewhere that they will build a tank to your dimensions but I have not verified that. The advantage that I see would be that you could have it built to fit under a specific tonneau cover.
