Outer Limits 4x4 Board

I had a service carried out on my Landcruiser and was informed that due to the number of K's the vehicle had covered (290,000) that the fuel lines need to be replaced. Is this common practice ?

Which landcruiser? AFAIK the injector lines on the 1HDFTE are a service item at 150,000km intervals along with the timing belt.

Or is this referring to the flexible hoses that feed the filter and the pump?

They are scheduled to be replaced at 150k, but at something like $700+ most people skip it...apparently Toyota was being over cautious and they seem to last a lot longer than that.

Id say the Rubber Hoses as the metal ones would only need to be flushed to get any scaling out

The Crusier is a 1HFDTE, and the quoted price was approx $700, the timing belt was replaced but not the injector pipes, I don't know if they were replaced at 150,000 as the car was not in my possession. I will bite the bullett and have them replaced. Thanks for your replies, your responses have been most helpfull.

Geepers $700 for a timing belt and some pipes, The Bundy tube to make those pipes cost about $2 a mtr

it's the high pressure injector pipes between the pump and the injectors not the sort of thing you can knock up your self they are worried about cracking from the high injection pressure used on teh 100 series

i have not actually ever heard of any failing i think i will wait and see how people go
my 100 series 1hdfte only has about 60k on it and will probably only do 20k per year so i have some time to find out if the ever fail

the 79 series with the 1hd fte does not have this called up in the service interval

I read up on them because I had one at work that was due for them, some people have gone well over 200k with no issues yet, so we'll see what happens I guess.

I still can't see how they could be thinking of Replacing them.
Unless there a inherant Problem with them Craking ,I doubt it has to do with Pressure
Theres Some old Toyota Diesels Running Around Mines Done 330,000

Because they running a far higher pressure then older type injection systems. Not sure what the 100 series run pressure wise but I know common rail diesels are running something like 30 000psi, if you cracked an injector line that was under pressure the spray would chop your arm off no worries.

But why do the 70 series not call for the same replacement interval when they run an identical motor, sans intercooler?

Dunno ask Toyota. Maybe the they run lower fuel pressure, who knows
