If the nozzles get swapped, the trigger won't start a fuel flow. This is because the actual diesel nozzle that remains in the petrol position holds the emergency stop flap in. To put the wrong fuel in a tank requires the wrong nozzle in your tank and the wrong pump has to have an empty nozzle receptacle.

It sounds like there must be a sensor inside the fuel pump "box" that knows if a fuel nozzle is sitting in one of the nozzle holders or not? I recall with older pumps, there was a lever you had to mechanically flip down or across the nozzle holder to get the pump going once you had removed the pump nozzle from where it would normally rest. Then to put the nozzle back in place, you had to flip the lever again to get it out of the way and this would also shut the pump down. Now I note that there are no flipper levers any longer across the nozzle receptacle so I guess there must now be some sort of sensor behind the nozzle holder location.

Since this thread started, I looked at our local fuel pumps. I see that for the petrol pump, while there are 3 grades of petrol, there is only one shared nozzle and hose. This theoretically means a hose full of the other grade could be pumped into ones gas tank before the desired grade entered, but that is a minor thing.

The diesel hose if mounted on the same "box" is always a separate hose and nozzle. Most often however, the diesel pump "box" is separated from the petrol by some distance and often on a distant island. I noticed this is very true of one of our local independent fuel retainers - all his stations have the diesel pump separated from the petrol pumps. I guess over the years, he has gained a good understanding of his client base.

Here, the problem is not the diesel guys; it is the petrol types looking for the cheapest price in the station.

I had it towed to a LR repairer in Gympie, who told me to expect between $7k and $11k as it will need new injectors and high pressure fuel pump.
They drained the tank, changed fuel filter, blew out the fuel lines, and bugger me it started. They believe that because I still had 1/2 a tank of diesel that I may have been lucky. When I got home I also changed the oil and filter and it has been running great, probably a bit better as I think the injectors are cleaner.

My question is, apart from changing the engine oil and filter and all the above, is there something else I should be doing to it that may have been affected by my stupidity??

One thing that I have noticed since I added the wrong fuel is that my fuel economy around town has come down from exactly 10.0 liters to 9.4!! I presume the unleaded has cleaned the injectors. There has been no other issues so I guess I'm pretty lucky.

I spoke too soon! My High Pressure fuel pump died yesterday and have been quoted $2700 for parts and labour. Sounds like a lot, but I don't have much choice as it was towed to my usual LR repairer. If anyone else has had it done, could you give me indicative pricing please?

Out of curiousity, could you not get a HP pump out from the UK and just have the bloke fit it ?
Have you compared the part prices ?

Just interested.

That sounds like a pretty good quote to me. There is a lot of work to remove and replace the HPFP. Just cross your fingers that there are no metal bearing fragments sent with your petrol-diluted-diesel - as that will mean possibly replacing some injectors down the track.

G'day Fitzy2011, I have my D3 booked in for new H.P F.P. ,after issues when towing big van up hills. Initial quote from independent L,R northern suburbs of brisbane, was less , if i recollect rightly, but then i have been known to recollect wrong.

Must get my bride to e.mail them , as they suggested other expensive towing mods as well.

Your probably right, but I need it back ASAP so I will just have to go with it. The repairer I use has been good to me in the past, so I will accept that he is not getting stuck into me.

When I originally added the unleaded I was amazed that I got away with it, so now that I'm having issues I'm not surprised so if other issues occur ill just have to deal with it. I like the vehicle too much to consider changing it so as it was my fault I'll fix it when and if it needs it.
