    I've never actually done it but I often wonder what happens if we do run out. I know in the old days it was OK to run out of petrol; you just poured another gallon into the tank. But I seem to remember that running out of diesel was a bleeding job (no pun intended). Is it still the same or do modern engines have some sort of cut off valves that prevents all the bother?

    The simple answer is, some will self prime, and some wont.

    I thought all modern diesels self primed. They drain down when you turn the engine off so the fuel line isn't left pressurised and the same process that repressurises the fuel at start will prime the fuel system if you've run out?

    the mk7 transit can be very difficult to get away if you run out of fuel.. even changing the fuel filter can lead to problems if you don't brim full the new filter before trying to start it..
    that's my experience anyway.

    I will have to be careful with my mk5 then. My mondeo starts fine after running out thankfully.

    No not all self prime, Fiat/Peugeot?Citroen have a priming pump in the tank that pushes the fuel up and the system can self bleed but Ford, Renault and Mercedes to name just 3 don't have the primary pump and will not self bleed, Fords are notoriously difficult to prime.

    And the diesel systems do not drain down when switched off.

    You have to be careful when you change the fuel filter in a Vivaro, well the 53 model

    You have to follow the instructions otherwise is a pain so they dont self prime

    They might depressurise between the common-rail & the high pressure pump but the actual diesel line from tank to pump is always full.

    Running out; doesn't bear thinking about for me in any vehicle:xsad:(n).
    Just in case you do run things close with fuel, here running out is actually an offence.

    Not your problem if you have decent breakdown cover.

    No breakdown cover in Spain for a local, means no insurance. I believe its compulsory with your insurance, that's why its illegal to tow.

    [QUOTE="dave newell lvs, post: 1223685, member: 4733"but Ford, Renault and Mercedes to name just 3 don't have the primary pump and will not self bleed, Fords are notoriously difficult to prime.

    Not quite, my Renault master 2500 cc 2008 G9U engine has a low pressure pump in the tank and a squeeze ball by the fuel filter plus the high pressure pump on the engine,
    But you would be foolish to run dry as the high pressure pump gets it lubricating from its fuel and would reduce its life if you tried to self prime only,
    Basically don't run out!

    Yes they do have some that'll have you falling about. :)
    Another one to catch you out is that it is illegal to wash your vehicle except in the garages & stand-alone car washes. That includes in your own fence & gated property !! :xlaugh:

    Hi.
    It costs the same to FILL a half full tank,as to fill a tank HALF full... Here endeth the "Umpteenth" things to no about transport LOL !!!
    You will find,that if the Red "Low fuel" light starts a winking miles from anywhere,serious damage can be done to the drivers seat,as your buttocks start trying to eat it.,. N'uff said.

    My 4000 th. post says......

    OH how true!!! Happened to me in Spain a couple of years back.....in the sodding dark ! Pulled on to the closed garage forecourt in the back of beyond and stayed the night until they opened ! Now that's wild camping !
    Lesson learned, always fill up when down to one third full !:notworthy2::notworthy2::notworthy2:

    I may be wrong ( it has happened in the past ) but if your battery gets tired while self priming do not attempt a bump start. I am led to believe that is a big no no with modern diesel engines ???

    It is a definite no-no with the transits, they've hydraulic chain tensioners & the lack of oil pressure & a jump start will in 9 out of 10 cases do damage.
