good afternoon all

as the topic says where is the best place to mount it, where it would be accessible for reset and not too sensitive
looking for all suggestions

Engine lid hinge....just like 80's Ford's do.... they just clip on

Here's a cheap one that'll work... $9 if you do not already have one

The racecar inertia switch...which is SCTA rule book required!!!

Mounted on the trunk firewall between wiper motor and master cylinder.

The wires going up out of the picture are looped from the fuel pump.

If you can slam the door extra hard and not trip it that is perfect.

I am going to mount mine up where the voltage regulator was mounted to keep wiring short to oil pressure switch. Both will control the electric fuel pump.

On my 66 Corsa 140 with AC, I mounted mine where a typical spare tire is mounted on a non-A/C car. The wiring is in series with the oil pressure switch which is at the rear of the engine and thus kept the wiring short. Either the oil pressure switch or inertia switch can shut down the fuel pump.

On my 64 GB I mounted the inertia switch along the front shroud and is also mounted in series with the oil pressure switch. I mounted the engine cover which is normally screwed down with a couple of hinges to allow better and quicker engine access, and if I drop the engine lid down, it will cause the inertia switch to trip.

As far as an inertia switch goes, I used the Clark's inertia switch. I found some cheaper from various sources but I wanted to make sure it was a quality switch. It is the exact same switch that is mounted on my Lotus Super 7 race car which is also approved by the SCCA and NASA racing groups.

I'm sure there are a number of places you can mount it to suit your needs as well as maintain safety.

Mike:

I appreciate the additional locations for its mounting. I will consider them, when I get to the wiring of the circuit.

I forgot to add that I also mounted on both vehicles a small bracket under the dash with a push button momentary switch and an indicator light wired to the fuel pump. The push button switch is a priming button to activate the fuel pump if the car has been sitting for a while and you need to prime the fuel lines and carbs. The light will light up when the fuel pump has power. The advantage to this is that you can monitor when the fuel pump has power. One time I accidentally dropped the engine lid down hard on the 66 Corsa and that tripped the inertia switch. I started the engine without noticing it but it died shortly afterwards. I noticed the indicator light wasn't lit and quickly figured out the inertia switch or oil pressure switch had opened up the circuit. By pressing down on the inertia switch and hearing it "click", I realized what happened. By the way, the priming button sure speeds up starting a vehicle.

This topic got me thinking...

Do an inertia switch and a rollover valve basically do the same thing? (That is, stop fuel flow)?

I've replaced a couple rollover valves in my AMC Eagles...

If so, would there be an advantage to installing in a Corvair (with mechanical fuel pump)?

Melb-Mike,

I was thinking of mounting one under the dash as well. Seems like a more convenient location for resetting than the trunk or engine compartment.

Do you have a picture of how you mounted it? It might give me some ideas.

thanks,

I'm in North Carolina at this time and will be getting back next week. I can take a picture of the one in the Corsa and the one in the GB. Having a priming switch sure helps when these sit for a while. The pilot light also is a good indicator that the fuel pump has power going to it.
