    I read what you said about doing propane conversion kits to your rigs and I was interested in doing this to mine in the place of a fuel injection kit. I read the article in the June edition of Four Wheeler about doing the conversion, but they didn't list any prices or anything. Also what are some of the draw backs of the conversion? I heard they are hard to start in the cold. The truck will be a partial daily driver till i get some a wagovan or something that gets over 10mpg for the city. /forums/images/graemlins/cool.gif /forums/images/graemlins/cool.gif

    I am daily driving mine right now due to seperation with spouse
    that was what caused me to convert it to propane

    I think the easiest/best route is to use a carb manifold with a used OHG system

    we did just put a impco 300a dual fuel capable system on my brothers bronco
    bought used and pulled it himself so total cost was time + $250cdn purchase price
    I want to replace the lines on his so that will add $100
    it doesnt get cold enough here for me to test the cold

    start problems
    at -40 the propane will have zero pressure
    I bet that would suck for starting

    it takes a few more revolutions to start then my Holley(it was very quick to fire)

    propane is 'stupid simple'

    I am feeling a power loss on hills
    but I have not done the timing yet and have disconected the vacuum advance, at the advice of a propane savvy friend, to keep total timing lower until I get around to addressing the timing

    the hardest part is tank mounting

    propaneguy is ok if you do not want the hassle of hunting used stuff down.
    his pricing on the tanks is more then I got an entire used system and dual tanks for ($250cdn).
    I wouldnt hesitate to pay his $300cdn for a 'firewall forward' OHG system, just to avoid the searching for used stuff locally
    but that still leaves you looking for tanks

    you need to see what restrictions your gov has in place
    here they require you to use 'certified' lines
    the lines are total junk but have a sticker that increases the price to $10 a foot plus $15 for ends
    I used Aeroquip 1053 line in -6
    it is rated for 10x the pressure of the certified line
    rated for some pretty extreme temperatures
    rated for gasoline/crude oil/ etc etc
    I used reuseable ends, trail repair friendly, so I could get the lines perfectly routed
    I have more in new lines then I paid for the system
