Roush Propane Racer Tubular Cage

Let's talk safety. First, the pressurized tank is essentially surrounded by tubular cage elements in the trunk to protect both the tank and its fittings. Also, because propane is heavier than air and would therefore sink in the case of leakage, the trunk floor is both vented and has a blower. All elements of the fuel system are spec'd to deal with the necessary high pressures, and all tank orifices have excess-flow valves, which would automatically shut off in the case of a leak. The -10 feed and -8 return lines are made of Teflon, because propane would leak through rubber lines. Even the transporter trailer will have a leak-detection sensor and a means of evacuating any such leakage. View Related Article
