There is a discussion about this on the Landracing website. It's obvious that
at least 2 folks have been using these switches and the rest of us have 1+
years to figure out what to do.
Holley blues and Mallory 110's do not draw high amperage and only ask for a 7-8
amp fuse. This style of pump could probably be used without a relay. Dan stated
on landracing "proof of excecution" and that may be a problem as I don't know
of a practical test; maybe Rick does. To me you could mount it on the frame
next to the pump and it would do what it needs to do in some kind of an impact.
I can't see it activating in a spin but on an enddo it would do it's job. I'm
going to "wait and see" before anything but am definately leaning towards the
FOMOCO.
