2020-03-20 - Fuel Cell Displacement Blocks

Q.
The listed stock capacity for our car is 16 gallons.
We would like to utilize a SFI 28.1 rated fuel cell for safety reasons.
After an exhaustive research process, we have discovered that a SFI 28.1 fuel cell with a capacity of 18 gallons is not available.

1. Can an SFI 28.1 Fuel Cell with an advertised 22-gallon capacity be installed that has an actual total capacity of 18 gallons?
2. If so, what does ChampCar Tech feel would be the safest and best mean(s) and method(s) for additional internal material(s) to bring the overall capacity to 18 gallons, thus adhering to the "stock capacity +/- 2 gallons" found in the BCCR?

 

A.
2020 BCCR v 3.0.0.
9.10.2.3. All fuel cells must have FIA-FT3 (or higher) or SFI-28.1 certification.

Pyrotect makes some 18 gallon FIA FT3 cells.

Yes, you can run a 22-gallon fuel cell. 
There are fuel displacement products you can use to get down to 18 gallons.
Be prepared to show the displacement blocks at all times as tech may request proof of install.
