Thread: Td5s and Petrol just dont mix!

If you only drove five kms in it, at ten or so kms to the litre, you probably didn't actually get all that much petrol into the system.

Hmm, except for whatever overpressure got sucked up and sent back through return lines.

Thanks for all of the replies chaps... I don't feel quite so much like a pillock anymore.

I think the Td5 is definitely smarter than I am! And it wouldn't surprise me either... she just continues to impress.

As for the return lines, I think the filter caught most of it. When I emptied it the day after there seemed to be a fair quantity of petrol diesel mix. It fairly spewed out of the bottom, rather than the usual trickle.

Anyway... All appears to be well, and it will hopefully stay that way!

I can recall reading in an interview in a Pommy magazine with one of the project engineers that because TD5s have unitary injectors they can run on multi-fuels.
Apparently the Yanks run them on Jet A (kerosene) in Iraq and LR got the contract because of the capability.
While petrol is not Jet A , it highlights that TD5s are more tolerant than common rail diesels, as they do not have a pump which requires the lubricity of diesel to live more than a few seconds.

Thanks for that Philip A, it's amazing how things happen, a mate of mine was down with our mechanic and he got talking to an older guy helping out the mechanic which is ironic as he taught him everything he knows about Landrovers, anyhow he also was talking about how the US Army used kero in these motors.
Would love to get a hold of the article it would be a good and interesting read.

Well, I've done a few thousand k's since I filled the Td5 up with petrol, and it seems I might be finally facing the consequences... then again, it might just be coincidence.

Lately, when I turn the key to heat the coils, the fuel pump is whining as it primes. It's not a painful, or even a particularly loud whining, but it is whining nonetheless. And it only seems to happen after she's been sitting for a while - like first thing in the morning, or after work.

I was wondering if this might indicate that the fuel pump is on the fritz? And if so, how long might I have before it just throws in the towel?

I should also let you know that I serviced the Landy myself on the weekend. Is it possible that perhaps I've just let some air into the system when I replaced the fuel filter, or anything of the like? Rookie mistakes, I mean.

As always, any help and advice is greatly appreciated. And if this is the result of my erstwhile stupidity, I'll take it on the chin... I guess it's one of those self-correcting faults, after all.

Cheers,

Yer, I've filled my Mazda T3500 with ULP. I drained it at the servo as soon as I realise my mistake, one of my drivers did the same thing at the same pump a month later and didn't pick it up 'till clouds of white smoke billowed out the back heading down the highway.
Nowadays I always look for a diesel only pump and not one of the modern 3 in 1 combination pumps.

How many Kms on your car Tika?

Could be just a coincidence. The fuel pumps seems to need replacing every so often even if you don't do the petrol thing. Mine is making similar noises at 120,000Kms and no petrol has ever gone through it.

It's just ticked over 90,000kms Spudboy. It's been about 5000kms since I filled it up with petrol.

So do you think it is on its way then?

Also, does anyone know how I can get the fuel pump out without the LR-19-009 (the special tool for the locking ring)? Will a gentle tap with a screwdriver and a hammer do the trick?
