Fuel Cell Foam Is a Service Item

Fuel cell foam deteriorates over time from exposure to fuel, heat and repeated use. As the foam ages, it can begin to break down and lose its ability to properly control fuel movement inside the cell.

Degraded foam can also create debris within the fuel system, potentially contributing to restricted fuel flow and fuel pump or filter problems.

Porsche Motorsport recommends replacing the fuel cell foam every two years.

Replacing the foam as part of scheduled maintenance is considerably easier than dealing with deteriorated foam and fuel-delivery problems at the track.

Updated Gray Fuel Cell Foam

Demon Speed uses an updated gray fuel cell foam with improved resistance to deterioration and breakdown compared with the original-style foam used in these fuel cells.

Fuel cell foam is continuously exposed to racing fuel, heat and repeated use. Over time, older foam can deteriorate and begin to shed material into the fuel cell.

The updated gray foam provides improved durability while maintaining the fuel-control and safety functions required in a racing fuel cell.

Precision-Cut Complete Foam Kit

This is not generic fuel cell foam that must be cut and fitted by the installer.

The Demon Speed kit is precision-cut specifically for the Porsche 991 GT3 Cup and the 100L fuel cell used in the 981 Cayman GT4 Clubsport.

Individual foam sections are numbered to aid installation, making it easier to correctly position each piece during replacement.

Installation guidance is included with the kit.

Why Fuel Cell Foam Is Important

Fuel cell foam performs several important functions within a racing fuel cell:

• Helps control fuel slosh during acceleration, braking and cornering
• Reduces rapid movement of fuel within the bladder
• Helps maintain more consistent fuel delivery
• Provides explosion-suppression properties within the fuel cell
• Helps maintain the intended safety characteristics of the racing fuel system

Because the foam remains continuously exposed to fuel, its condition should be considered part of routine fuel-system maintenance.

Fitment

• Porsche 991.1 GT3 Cup
• Porsche 991.2 GT3 Cup
• Porsche 981 Cayman GT4 Clubsport – 100L Fuel Cell

All 991 GT3 Cup cars use the 100L fuel cell. The 100L designation is only necessary when identifying the correct 981 GT4 Clubsport application.
