tachometric relay or fuel pump safety switch where can I get one???

[vibe65]

I have recently fitted a holley blue fuel pump and its wired through ign circuit via relay. Ive done some research and as a safety thing im after a tachometric relay. It need coil pulse to send signal to fuel pump relay so in the event of a crash and im knocked out the fuel pump will stop as soon as engine stalls. As it is fuel pump runs whenever ign is on.

Problem is while in google land everyone says just go to a local auto elec and they will have one for $20 buck ish or go to a wreckers. I went to 3 auto elecs yesterday plus repco and bursons and no one knew anything about them or where to get them. So does anyone know where I can get one or if I go to wrekers which cars run them and where they are in car. I think maybe VL commodores had them???

Thanks

Go to an LPG fitter.  Modern LPG installations have the same sort of thing for the same reason.
