welcome IHG Im no expert at all but if you have changed sensor's and harnesses they arent the problem I would look a little more basic because I am a simple person how about removing the negitive from the chassis cab ect ect and make sure the connections are spotless emery the frame under connections give those lugs a real good tug make sure they are well attached if it has a intermittent problem I doubt its a sensor just my thoughts Paul Oh yeah gotta learn to smile lifes to short not to

top job there Vlad keep up the good work and thanks for sharing Paul

top job there Paul

what a beach buggy gotta love that Paul

nah mate he gave them a bath

Im sure we have all worked with pricks like that they make for along day Paul

Steady on there big fella 99% of truck drivers in this wide brown land were them although we dont call them flip flops Aussie slang "pluggers" unless of course your on that stupid show out back truckers dont even get me started on that crap we dont have truckers in Australia there called truckies Paul

If it is like this it would be a D7 E Paul

welcome aboard Paul

mate you need to wait for the crowd to go home before trying I find things so much easier if people arent watching me Paul

we called them a Mid Liner out here I dont think they were a bad little truck seeya Paul

Yeah Im not sure how to explain this but it only has one H pattern I think thats what you asked 3-4 , 5-6 , 7-8 , 9-10 , 11-12 as said above you can drive it as a 5 speed and at the flick of a switch at any time you make it into ten I think there a dream to drive just me not everyone agrees but they are allowed to be wrong LOL but they are tough and bullet proof Paul

its just like driving a normal ten speed only ever use the second stick for deep reduction I find them a lot easier than a road ranger to drive but thats just me perhaps Im lazy and dont like shift the stick as there is only four shifts from zero to top speed Paul

Ok Dave all I know is this is fairly standard across all diesel motors as to taking the return line off the pressure relief valve you wont catch an fuel there because the fuel is running back down the supply line to the tank so it will be trying to suck fuel in perhaps you could screw the return line into the bottom of the tank for a few days and see what happens or maybe remove it and put it in a bucket of fuel when you stop to see if it then starts ok you would have to remove it with the motor running but I think that missing bit of line in the tank might hint towards a possible problem good luck Paul

never no Vlad he might start his own state Mack'sville Paul

looks like its being to one of those US fast food places and being up sized to SUPER SIZED Paul

nice and shiny, healthy little poddy with a serious look on it's face Paul

Dave this the way I under stand it but as always I could be wrong First pic is with motor running as you can see the fuel comes from the tank thru the primary filter then to the lift pump the it goes to the secondary filter to the injector pump through the the motor uses what it needs whats not used goes out thru a Tee to the puff limiter and air start if fitted are supplied under pressure and the left over fuel returns to the tank now when the motor is off (second pic) the fuel siphons back down to the tank and it is meant to drain back thru the lift pump and siphons the fuel up from the tank thru the return line as the return line reach's to the bottom of the tank thru a tube inside the tank now what is most likely happening is there is a slite leak in the return system somewhere most likely thru a fuel line or perhaps thru the air start puff limiter but one thing I think for certain is it is in the return side of the fuel system The fact it runs fine eliminates the supply side of things as all you have looked at is the supply of fuel and it all checks out it has to be the return I have learnt this by going down the same path as you it wasnt till someone explained it like this that I fixed the problem mate I hope all this waffle helps and one thing to remember tens of thousands of these trucks run fin every day with out any fancy fuel supply system seeya and good luck Paul remember its a Mack enjoy the ride hey Dave what part of this wide brown land are you at brother ?

thanks for that you'll have to excuse me and my dumb questions as it dosnt snow here dosnt get below 20 degrees c in winter thats 68 f for you blokes Paul

some people are a bit slow that mighten even work Paul

I have a real dumb question when it snows is the air muggy ? is it ok to leave metal bare for a few days or is there to much moisture in the air and does it get lite surface rust top job Mr Wobblin Paul

all I can think of is Goofy in the old Disney cartoons Uh Oh there goes my tyre Paul

mate if your engine runs fine and holds prime when running but looses prime when it is turned off the problem is not in the supply of fuel to the pump the simple fact that it runs fine should tell you that It only leaves one other spot for air to enter the return line when it syphones fuel back when not running !! so the problem is in the return line to the tank or the tube inside the tank has a crack in it you can put all the non return valves in the delivery line you like it wont make any difference this do dah aint gunna fix it either you gotta fix the problem not the symptom I can draw picture to explain whats happening if you like Paul ps Im not trying to be a smart ass if I am coming across that way I apologise Paul

as above it was amazing what could be done back then I reckon we might be in a world of poo if the same had to happen today Paul

never heard of such a thing I guess $600.00 isnt a lot of coin to blow if its crap ?
