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

[Transit720]

Transfer Flow is currently in the prototype phase and has reached a key decision point.

At this stage, the tank is designed to hold 44 gallons. They had initially hoped to offer a larger capacity, but available space has limited the options. Gas systems are also more expensive than diesel systems due to their complexity, which includes specialized fuel lines, extra emissions canisters, and the need for extensive testing.

To help guide the next steps, TF asks for your input on the following:

1. The estimated retail cost of the currently designed 44-gallon tank is $2800. Would you be willing to invest this amount to increase your fuel capacity by 13 gallons?
2. We are also considering increasing the tank's height to bring the capacity to approximately 50 gallons. Adding height requires a larger sending unit and adds approximately $400 to the total cost. Would this option be of interest to you?

Slight drift (but still related to more gasoline for a Ram CCSB)
Running 40s precludes me from using the factory spare location for a tire, so I am installing a Summit SUM-255028 (replacement for a Ford tank *C3Z9002AA**) 40 gallon tank in that location (for 71 gallons total). A great fit other than I want to move the exhaust to in front of the rear axle (maybe not necessary, but safer?).

With the Rambox option, it is a great place to mount the filler (Perko 1318DPGBLK Polymer Vented Gas Fill) without 'harming' the side of the bed as a great straight shot to the filler neck of the fuel tank, and even 'locked' when the tailgate is on and locked.



No projected progress until after the Oregon rainy season, but I will post a 'how-to' when completed. (using a transfer pump to fill the factory tank, with a sender and gauge for the aux tank, and selective switching)


Tank $376 (on sale)
Filler $ 25
Gauge/sender $30
Pump $46
Pressure switch $18 (auto shut-off for low transfer pressure)
Switching $10
TOTAL $505 (12.62 per 'extra gallon' of fuel)

I'll be curious how you do that tank. Please post up on the build up.
