Austin, the stock-location Fuel Cel, what is the volume it holds?
It is 1" shorter, height wise, than OEM, wonder if two of those cels can equate to 1 oem tank volume?
Website does not contain volume info, which is ---really strange since its basic requirement.

Answer is 6 gallons.
I personally really dislike the typical race-fuelcel that is located in some race and rally evos, either in liu of spare wheel well, or between the rear strut-towers.
OEM low-down location is perfect centralized location to minimize impact of fuel-level change on handling, and also keeping weight low and centered.

The issue I have with these small tanks is they're......too small lol. Only two ways I see it.
1. Install a trick surge tank setup to add 2-5 gallons
2. Install a proper fuel cell in the OEM location.
Now ATL does make a bunch of OEM evo fuel cells rated to FT3 or 3.5 per rules. 72L is about 19 gallons which is PERFECT, and it would seem the neck is on the wrong side? but it's otherwise complete. Did one of ya'll get a price on this unit?
If you do it like Sierra Sierra then of course it's bomb lol. Speaking which having said "bomb" behind a metal bulkhead such as the rear seat is also good.
Provided its not worse, and does shave some weight, it also now frees up a nice cavity in a great location to run any ballast you may need to.
For sure. Zack brought it up too that running a small tank lets you run enough fuel without as much fuel slosh which seems like a win for AX. My next round of stuff should shave about 70lbs from the front of the car which is putting me danger close to needing ballast even with the heavyAF 18x12 and 315s.

Ummmm 70# from the front!? Do tell! Are you moving radiator to your trunk? And what else bc 70# is like a lot lol. Perhaps different thread and discussion before I derail this one but ahhh that is going to be awesome!
Well I'm a tad late, yea the ATL cells are suuper pricey. It's not cheap to get stuff FIA cert'd. If you're doing races that last 30+ minutes the 6 gal stuff is drfinitely too small but for guys doing TT, time attack, AX etc. it's a great option IMO.
The biggest appeal to me with the STM/FCS cells is location, weight savings, keeping a useful level sensor, and not having to run a siphon line anymore so you can run a large fuel pump without siphon issues.
I wanted to get one this winter but time and funding didn't permit. Maybe next year.
you can fix most of the slosh issues on the original tank and get rid of the syphon by running a second pump in the passenger side of the tank instead of just the pickup... I made just such system.. stock level sensors and all..
