TNblufffarm Posted August 12, 2021 Share Posted August 12, 2021 Looking at possibly getting an auxiliary tank for the bed of our 22' F350srw (when it arrives). Considering the 46 gallon ATI. Can anyone chime in with their experience with this one or something similar? It's a gravity feed tank. Thanks. Quote Link to comment Share on other sites More sharing options...

DecodanMcQ Posted August 16, 2021 Share Posted August 16, 2021 (edited) I have a gravity feed 41 gallon in the bed of my ‘16 F-250, 6.7. Truck only has 28 gallon tank so this worked very well for me. In fact I will be moving the tank to my ‘22 F-350 CCLB 6.7. Dealer didn’t care if I take tank before trading. This new truck comes with 48 gallon tank so I will be at 90 gallons total. Now, all that said. I originally set it up as gravity feed through the fill neck. However it would overflow the stock tank. So I added a 12 volt inline fuel pump to the gravity feed line and also put a ball valve cut off that I could reach via rear wheel well. I leave the ball valve off most of the time and just use the stock tank. Then when I am going on a trip I open the valve. When I get to 1/4 tank on gauge I use upfitter switch to turn on fuel pump and let it run 15 minutes or so. You do have to be careful not to forget and force overfill stock tank. And remember to turn ball valve off when parking for night. Also, the auxiliary tank fits under the hard tonneau.

jeffhunta Posted August 16, 2021 Share Posted August 16, 2021 Has anyone replaced their gas tank for a larger one? If so, which replacement did you go with? Quote Link to comment Share on other sites More sharing options...
IUEC135ELEVATOR Posted August 16, 2021 Share Posted August 16, 2021 (edited) I wonder if I could get a toolbox/fuel tank for gasoline....7.3 engine truck. But to carry 50 gallons of 87 in the truck bed would probably break 20 different laws. Just looked...apparently you can get them approved for gas.....(I must have one!)

Edunn37 Posted September 13, 2021 Share Posted September 13, 2021 According to someone on the Ford Tremor forum that has a contact at TransferFlow, they are working on a replacement tank for the 7.3. I'm not sure of the capacity, but I would not expect it any time soon since I think it was just approved for development in April. I'm sure there is a lot to go through for approval.
