supplier please for pipe from 4108 injector pump to injectors

[pcatterall]

All the pipes from my engine filter to the injector pump and injectors are steel. They have been there a long time and I would like to be sure that I can repair them when and if they fail!!
I can see how I could replace the lines from filter to pump but the ones to the injectors look a real pain.
I would welcome any info on a supplier, if I can get them I may still look to see if I could make up temporary ones in copper(need to have the materials on board). The steel ones weave in and out of so many fittings that I think the only way to do a proper repair would be to lift the engine and do them all at once. A temporary repair in copper could be fitted external to these fittings; inelegant but it would buy some time?
So... info on a supplier welcome and also comments on the pros and cons of temporary repair in copper.

A temporary repair in copper might work for a while, but the pressures are really too high for copper, and pulsation causes work hardening which can result in the pipe splitting. You could do a temp repair in steel as easily, surely?

Nope - you need the correct pipes. 175 bar takes some sealing.

Try hindles - large agents for Perkins at one time:

Doesn't work. AS TK says the pressure is too high. Even a copper injector pipe will burst.
You can, however, get flexible injector pipes. If you're worried about an injector pipe breaking why not buy a flexible pipe which is long enough to replace your longest pipe as a get you home measure.
We used to carry one in each breakdown truck, but haven't replaced them for years - we haven't come across a burst one for years.
They are still available - just checked with Mr Google.

Thanks guys. I had not realised that I could use/get aflexible hose that would do the job. It seems strange that copper pipe wont stand the pressure but a flexi will. I thought the flexi would just be plastic with a woven metal cover. I take the point about case hardening and yes I Guess I could form that size of steel pipe to the right shape.
But I'm off to the recommended flexi site now now!!
Thanks again.

I have worked on diesels all my life, in UK, in Africa and the Middle East, with a 3 month supply line. I have never changed an injector pipe! Dont worry about it!

Stu, ahh well a pipe on my last 4108 did develop a crack and had to be replaced ....so there!!
Cant find any site for flexi pipe yet though.

Injecter pipes can break normally at the ends (vibration). The good news is that with care you can bend them by hand or use a small pipe bender so carry an extra long spare.

Changed a few on volvo diesel truck years ago, TD101/2/3 engines, volvo actually did a get you home steel pipe which could be bent into any shape, seen a few go on the early daf tracks as well.
On my old 1959 land rover someone had repaired the snapped injector pipes with the brass fittings with olives, this was the high pressure lines and they didnt leak!

I had a Peugeot car that broke down with a fractured injector pipe. It broke off where the pipe was flared, ie where it entered the cap nut. The reason it did so might have been because it had been done and undone a lot of times due to a lot of engine/injector system bleeding or it might have been because the pipe had been bent into position after being bled with the cap nut tight, or it might have been due to not replacing the anti vibration clips owing to rushed work. I think the killer was bending the pipe with the cap nut tight but the other two things may have contributed. The RAC man came out with one he pinched off a different engine (a scrapper) a few bends later at it was made to fit, sort of. It got us going.

I have had to replace injector lines on a 108 before so it can happen, I carry a spare set on board for this reason.
The reason the lines "weave in and out" is because they have to be the same length, copper is a no-no.
Get a second-hand set, seal the ends and keep them on board.

If you find a supply, let me know please - mine have seen better days and I've not had any success locating replacements.
Thanks.

Ahh.. is that so?... one reason why mine weave in and out is to get around all the fittings!! and then of course more ( marinisation ) fittings are added and you have a right dogs breakfast!!

If the length is critical then I will have to measure one and get my spare to suit.
I will try Diperk as that is where I got my last one. That is from 2008 as I have just found my old thread of that date ( quite by accident as the search system seems diabolic)
Thanks all
