My car caught on fire for that very reason. Rear ended in the rain and it broke off a carb, cut the fuel line and broke the main kill switch. Fuel dumped on the belly pan and then a cut battery cable wire provided the spark. It made for an interesting few moments. We finally had to cut the fuel line wire and hose the car down to wash the fuel away.
There are no rules against running a separate cut off circuit as ling as the master works. You can also by inertia cut off switches in most race shop catalogs. Mark S.

Yes I know that it will be turned off when the master switch is turned off, but until that happens, the pump will be running. My concern is what happens when there is an incident and the fuel line between the pump and engine becomes disconnected. I would not want fuel being sprayed around in the engine compartment with all the hot parts in there. On the engines using pulse pumps, when the engine stops, so does the pump, but with electric, the pump will just keep going even with the engine stopped. I am making an assumption here that the car has suffered damage to the rear, and the driver is not in full possession of his extremities right after. If the driver can not turn off the engine switch, even if the engine has stopped, fuel could be being pumped into the engine compartment. Corner workers may not be able to reach the car immediately, (car is on opposite side of track with cars going by). Has anyone else thought about this much ? If so, have you come up with a solution ? I know that Pegasus has a $64 dollar solution.
