    What about a Crash Relay for Electric Fuel Pump

    I was reading http://www.mooregoodink.com/news/ove...years-of-toil/
    and also saw this http://www.summitracing.com/parts/rfw-cr92
    and thought it to be a good idea but my fuel pump is already on a separate relay.

    I know Ford has had something like this for many years on their vehicles.

    Seems like I could create the same thing for less money but I wanted to hear you opinions.

    I've heard of a "rollover switch" to shut off the fuel pump, but not a "crash relay".

    The Ron Francis switch must be an inertia switch.
    Here is their install instructions:

    My bet is it's less sophisticated than that.

    Looks like you could build your own for about $25 in parts instead of paying RF $112. I just bought the Jag sensor for $15 and a relay is $5 (already have some). I think this is a pretty good idea so I'll probably put one under my rear seat.

    Thanks for the idea!

    Another thing to add to my "options" list. Crash sensor fuel pump shutoff.

    Well I found a Ford crash sensor and pigtail so I am thinking of mounting it in the trunk.
    I assume the red reset button needs to be pointed up.

    Complicated stuff I don't need or want on a hot rod.
