Frequently Asked Questions
Why can't I use my stock fuel tank in a derby car?
Stock fuel tanks are not designed for extreme impacts and often have thin walls, exposed mounting, and poor baffling. They are highly susceptible to rupture, leading to severe fire hazards in a demolition derby, which is why rules universally mandate approved fuel cells.
What is anti-slosh foam, and why is it important?
Anti-slosh foam, typically open-cell polyurethane, fills the interior of the fuel cell. It prevents fuel from surging violently during impacts and turns, ensuring consistent fuel pickup, reducing vapor buildup, and critically, suppressing fire by limiting oxygen in case of a breach.
What are AN fittings, and what size should I use?
AN (Army/Navy) fittings are a standardized, high-performance connection system used for fluid lines in racing. For a 5 gallon derby fuel cell, -8 AN fittings are commonly recommended for fuel outlet, return, and vent lines, as they provide sufficient flow for most carbureted or low-pressure EFI derby engines.
Do I need a rollover valve for my fuel cell?
Yes, absolutely. A rollover valve is a critical safety device that allows air to enter and exit the fuel cell for proper venting during normal operation, but seals shut if the vehicle rolls over. This prevents fuel from spilling out of the vent line, significantly reducing fire risk.
How should I mount a 5 gallon fuel cell in a derby car?
A fuel cell must be securely mounted in a reinforced, protected area, typically in the trunk or behind the driver’s seat, away from direct impact zones. It should be fastened with sturdy straps or bolts to a robust frame or cage structure, often with a steel cage or box around it for additional protection against impacts.
