    graham may be on to it.

    the line between the cut off solenoid and the convertor is depressurised when I have this fault. This will create a bigger differential pressure across the cut off valve spool like I have noticed. I will check the pressure just after I stop to see if this is normal.

    Still, why is it only an issue at higher ambient temperatures?

    Pulled the guts out of the solenoid in the convertor.

    Quite a bit of crud in there with one obvious lump right on the seat.

    Cleaned, reassembled and started engine.

    Shut down and checked for pressure between the convertor and cut off. Heaps.

    I'll check it again before I start it in the morning to see if it is holding.

    Now, What sort of beer would you like graham?

    It's a tough choice choice - I'm partial to James Boag but being in SA I'm also fond of Coopers Pale .

    Glad to hear that you might have just "knocked the b@st@rd off" at last (to borrow the words of a famous Kiwi). Hope you really have nailed it and your vehicle is reliable again.

    I'm planning on visiting the mother in law in Port Noarlunga in the next few months. Maybe we could settle the debt at a pub then ?

    The higher temp may be tipping the gas up to a higher pressure and creating a leak that won't be there at lower temps.

    If you stand next to the bowser and it is just ticking over, let the gun go and listen to the bowser. After approx 30 sec you should hear a definite " click". Thats the excess flow valve resetting, then you can start again. The trouble with the LPG guns is that they have a flat valve and it lifts vertically which you cant get to open slowly.
    Thanks for the thanks
