    I think it's the way to go very easy to wire and it primes for 3 secs when relay gets power.
    Also has safety to stop pump if motor stops.

    That's all I use Davo - LPG safety switch turns the fuel pump relay on and tach wire is the trigger to keep it on !
    If you don start the engine within 3 seconds of the ignition switch on - the fuel pump will stop but kick in again as soon as you start it !

    can i ask ...where on the site?

    I have just spent 15 mins going thru all the pages of products and I cannot see any switch/product they list or sell
    that turns off the fuel pump when the engine stops

    If you use an ignition box (ie MSD 6), you cant wire straight to the coil + because the voltage is too high (they run 400+). I had success in my 253 LPG hilux just wrapping a length or wire around the coil->dizzy lead. It would pick up enough signal to work.

    Yes I am running a Crane Hi-6 ignition unit. I'll check the instructions on that to see if I can use the coild +
    What about using the Alt to trigger the saftey switch?

    I just used the tach wire from the msd - your crane ignition should also have a tach wire.

    The safety relay is designed to activate from an ignition pulse so becuase both the crane and msd fire the coil with 400 to 500 volts you cant hook up your tacho or the safety switch to the coil anymore so a tach wire is provided for this purpose !

    Thanks Mick

    Mick should I run the tacho wire to the tacho then to the saftey switch or should I splice the tacho wire off the ignition system into two wire. One for the actual Tacho and one for the saftey switch?

    Cheers Dave

    Ah, I didnt even bother to check that. I figured because the LPG safety switch went to the coil +, and tachos usually go to coil -, the msd tacho wire must be like a coil -.

    Found a switch guys $33 from here, there local to me. Blue LPG Donut tanks
    For referance you can not but this switch at places like Bursons ect.

    Now this switch will turn on for 3 seconds and then if no signal is recieved from the tacho it will turn off.

    My question is, I have all new engine, carby, fuel lines and fuel pump all dry. So I guess I will have to overide this saftey switch so I can prime the system?

    Cheers Dave

    Yep that's it Davo - you can (if your clever lol) wire in an over ride switch for that get purpose !
    Don't forget - you sill have to use the 30 amp relay to supply power to the pump and the safety switch operates the relay !
    Those safety switches aren't designed to carry a lot of current.

    guys.. am i missing something here?

    Davo's original post -
    Hi guys I was reading the Vic roads regulations on modifications as I'm currently putting in new fuel lines.

    What I read regarding the installation of an electric fuel pump was interesting. And it seems I need to redo the way the pump gets its 12V+

    The guidlines say that the pump must turn off if the engine stops. Now my pump runs off a relay which gets it power from the on position of the ignition system.
    So my pump will turn off and on with the ignition.
    But say the car was in an accident and the key was still in the On position but the engine was stopped, the pump would still
    be working.

    --------------------------

    ...from all all the stuff recently posted, I cant see how/where the pump is actually turned off??
