Charlie,
Today they use foam filled fuel cells with electric pumps, might be Waterman but not sure? They have check valves that close if the engine separates from the chassis - not sure what they use to cut power to the pump, other than a driver toggle switch to light off.
Here's Waterman link that explains their pump system, including a bit on efi systems - http://www.watermanracing.com/Pages/fuelpump25.htmlLast edited by rspears; 11-29-2011 at 12:40 PM. Reason: Added link

Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.
