    The lift pump runs from the cam.
    It's my understanding that if the lift pump is on the cam lobe the the lever will just flop back and forth and not pump anything, you need turn the motor over so the pump is off the cam lobe.
    Can anyone confirm this?

    Ran mine out of fuel twice, took approx 5 sec on the started to fire up.
    Just start it after filter/sedimenter clean and change, never been a problem.

    I ran out of fuel earlier in the year heading to Broken Hill, it ran out of fuel about 5 seconds after I said "I think the fuel guage has stopped working?". Luckily I had a jerry of fuel. Turned over almost immediately.

    Serge,L322's have a gauge,a warning light,a warning chime,a warning message on the digital display and start turning injectors off to cause a miss to let you know it's running out of fuel.My sister inlaw still ran it dry. Pat

    I have never run the 300tdi (disco) dry, but both the 110 and the IIA have twin tanks and I have run both vehicles dry once or twice by forgetting to change over in time.

    I have also run the IIA dry once because a passenger in the middle seat kicked the changeover switch to the middle position with her foot while getting in

    correct you will get something BUT... if you are pushing the lever far enough to make it pump while the cam driven lever is sitting on the lobe you run the risk of overstretching and busting the diaphragm.

    From bone dry it (which includes a replacement fuel filter that hasnt been pre primed) takes ~70 pumps... I know this because I suffered from a clogged pick up on the weekend my sequence of bleed (for a standard fuel line setup) is

    fill the tank (this assumes that its not a blocked pickup)
    crack open the bleed nut on the top of the filter head in the engine bay
    pump till fuel comes out of the bleeder and tighten it up (this should take ~55-60 pumps)
    turn on the ignition
    crack the line to the IP from the fuel filter (this is to confirm that the filter is not blocked OR you havent left the plastic insert on the filter, yes, Ive seen it happen)
    pump the primer till fuel comes out (should only take about 3 pumps)
    tighten up the line from the IP
    pump 10 more times

    Disconnect the fuel solenoid (your about to be cruel to the engine)
    crank it on the starter till the oil pressure light goes out
    reconnect the fuel solenoid
    hold the accellerator flat
    crank it till it starts

    you can disregard the bits in blue in most circumstances I do this as part of a full service because as part of a full fuel system service I remove and blow out all of the lines

    Do the Tanami on one tank and a couple of Jerries that should do it.

    well i did it tonight, ran out of fuel, but by this time was carrying a 5L container of fuel as i knew it was gonna come at some point, anyway like a few other posters i found to my surprise it only took a few seconds of cranking, which cant possibly equate to 50 odd strokes of the lift pump, i was very happy as it was dark and rainy when it happened, my old xantia would go flat on the battery if i tried it without manually priming, Land Rover is good for one thing i guess although it has a massive water leak! as i had just discovered with all this rain, (have only done 400km in this car) i think it is the rhs curved roof window
