Transfer Flow developing larger GASOLINE tank (factory-replacement) for RAM 2500/3500 CC Short Bed

[Transit720]

IMPROVED MILEAGE / RANGE is the works!

The project has only recently been officially initiated, but here’s what I’ve learned from Transfer Flow so far:

Tank will be developed for the CCSB 2500/3500. This is where most of the demand currently lies.

Availability date is difficult to predict, given the development, testing, CARB certification, etc. Ballpark guidance from Transfer Flow is that “gasoline projects usually take six months to 1 year to complete.”

Capacity is also unknown at this point. In general, the company likes to “shoot for about double the capacity”, but of course they are limited by the available space forward/aft of the OEM tank. As a point of reference, Titan’s replacement tank for the RAM CCSB DIESEL has 52G capacity, also vs 31G OEM. So, my guess is we see something in the ballpark of 50G, which maybe adds 200 miles of range for those of us hauling heavy campers and getting around 10 MPG.

Loss of clearance (breakover angle) is expected be minimal. TF says their tanks usually don’t hang below the level of the OEM skid plate. If I understood correctly, this means the bottom of the tank may hang 0.75” to 1” below OEM tank. Because the tank will be made of steel (specifically, powder-coated aluminized steel), Transfer Flow says no skid plate is necessary. TF told me they’ve not had issues with tank damage due to scraping of the tank. Clearance/breakover is an important issue for me, so I will be watching this closely.

I know nothing about planned pricing at this point. But, I do know that Transfer Flow has a steel replacement tank available for the F250/350 short-bed crew-cab. It is 58G (vs OEM of 36G) and sells for $2,730.

I will add more details to this thread as I learn them.

PS While I expect that this project will result in Transfer Flow bringing a tank to market, there is no guarantee. I think it would be helpful to let Transfer Flow know of your interest at:

In Oz, ARB make rotomoulded plastic fuel tanks for a few of popular models.
They are tougher and lighter than steel and never rust. Superior in every way.

Have you posted your roto molding process on line Peter?

Not here.
I make the simple sheet metal moulds and get a local moulder to make the tanks.
Threaded fittings can be added anywhere they are wanted later by spin welding.

I need one for a 1500.

I hope they get this tank built. I’m sure carb / evap will be the main hurdle.

50+ gallons in a crew short gas ram will be great. I’ve been considering a tundra instead of a ram for this exact reason.

Quoting Peter "I make the simple sheet metal moulds"

Your moulds are a work of art. Wow.

ps.....For those who mess with polypropylene of polyethylene plastic tanks, spin welding is a good DIY technique for adding threaded holes.

No doubt those are impressive looking rotomoulded plastic fuel tanks, Peter. However, in the USA, such a tank could be problematic. For example, those of us living in California (which is about 12% of the entire USA population), there's a requirement to get your vehicle inspected periodically for emissions ("smog check"). My understanding is that if modify your tank or anything else related to emissions, the modifications have to be approved by CARB (California Air Resources Board), or you will fail inspection and be denied registration renewal. Transfer Flow spends the time and money needed to get CARB approval for their tanks. So, this is part of what you are paying for in the cost of the tank.

No doubt their after market steel tanks need approval then also.
What is the difference?
The ones I make for my own use are approved by an authorised engineer.
These days, pretty much all small vehicles have plastic tanks. Large trucks often use aluminium to keep the weight down. This has its own significant problems with the risk of fatigue that is not present in plastic.

Help requested to keep this project moving along as quickly as possible!

I emailed with TransferFlow a few days ago and learned that they are using the 2024 Ram CC SB to design the replacement fuel tank. They need to validate any fuel system changes made to the 2019-2022 model years. (OEMs often change small details, even though they say the truck is "carry-over" from the previous model year.)

TransferFlow is looking for the following information on 2019-2022 Ram CC SB 2500/3500 (they already have the photos for the 2023 model year):

Pictures of:
· Vin Number
· Emissions Label
· OEM Tank
· OEM Emissions Canister
· Hoses (tubing between canister and tank)


If you are willing to take photos, please send them to Teri at TransferFlow. Her email is tbarry@transferflow.com

THANKS!

UPDATE!


TransferFlow's replacement tank is progressing. As of today, the tank is 50 gallons and is designed to fit the CC SB 6.4 V8 Hemi.


However, they are still investigating to ensure it fits the 2019-2022 model years. PLEASE SEND THEM PHOTOS PER BELOW!!!

More info to pass along regarding plastic tanks:

Plastic tank manufacturers won't offer replacement tanks for GASOLINE because of permeability. OEM tanks go through an expensive fluorination process to reduce permeability. Without fluorination, plastic tanks will not pass emissions testing.

More states are adopting CA emissions standards every year. Seventeen states have followed suit. https://afdc.energy.gov/laws/california-standards

I'll, readily, plead ignorance as I haven't spent much time examining the gas tank. Do you know if what they're looking for pics of is all visible with just dropping the skid (I have a 2500 w/ Power Wagon package), or do you need to drop the entire tank?

I did not drop the tank on my RAM3500, and I was able to get them all the pics they needed. So, I'd expect your experience to be the same (once you've removed the skid plate, which I don't have). Good luck and thanks for looking to contribute photos!
