You may already have something planned but food for thought.

Interesting, The reason I was going to use switches to control the fuel pumps is I'm planning on using a holley pump which has two internal pumps that can be wired separately. One can be used for cruising around and both can be switched on when at the track. Just did some research and holley makes a low oil pressure fuel cut-off. This way if a roll over occurs and oil pressure drops power will be killed to the pumps.
