Hi all, does anyone know if a larger capacity fuel tank option is available for the 2022 7.3 SRW crew cab with 6.75 foot bed? I had to fill up every 200 miles towing my RV last week, thanks.

Nothing for the 7.3 yet. We know that Transfer Flow is working on one, but it's a ways out at this point: https://www.fordtremor.com/threads/update-transfer-flow-replacement-tank-for-gas-super-dutys.4365/

Other option is an in-bed transfer tank, but obviously that's not as convenient as a replacement tank as you still need to stop to make the fuel useful.
 
The range is the number one reason I went with the diesel.
Absolutely! I know I will never make up the $8K engine price difference in gas savings alone, but the hassle of stopping every 200 miles to fill up when towing would get old real fast! Plus, the 1050 lb/ft of torque and engine braking is wonderful when towing. :cool:

I figure I will make up most of the cost difference in resale value, but if not, it is not that big of a deal for me as I was able to enjoy the diesel benefits while I owned it.

I did some research and it seems the reason why large tanks for gas aren't available is due to the larger evaporative emissions canister required in addition to a CARB approval or something like that.

Also learned that Transferflow put too much effort into making a larger gas tank for the F150 and then claimed poor sales, hence their hesitance to develop another gas tank on a different platform, although the Super Duty is a way better candidate than the F150.. I guess they missed the memo there.

One of the main reasons I switched my order from a 7.3 to a 6.7 this week. Couldn't risk a aftermarket tank not becoming available.

That’s true, but you can get a 36 gallon tank in a F-150 for heavens sake! Not to mention the larger gas tank that’s available on the long bed.
 
Transferflow does have a new replacement tank coming for Superduty with 7.3 - Just got CARB approval - see this thread to get on the list to get one - not cheap - but the only option if in Cali. They will start trickling out in August and build them too meet demand - however I think they have a long list of emails of those already interested, so may have to wait a bit to spend $2k to get one. I have had their tanks in several other trucks and they were great.
