Cold Start Injector Pipes?
Cold Start Injector Pipes?
Does anyone know the part numbers for the cold start injector pipes as I can't work it out from the ETK and mine were pretty much destroyed so not much of a reference.
Also where to get, can I just buy the pipe and reuse the ends?
Many thanks

Re: Cold Start Injector Pipes?
Just looked at my 323, one pipe from fuel distributor to cold start injector, warm up regulator has 2 pipes also from fuel distributor, maybe help figure out a schematic, if you're stuck I have spare ones but would prefer not to part with permanently to keep spare engine complete.

fuel line to cold start injector 2x M8 banjo, part no 13 31 1 266 618 (see note)
fuel line 1 to WUR M8 & M10 banjo, part no 13 31 1 266 617
fuel line 2 to WUR 2x M8 banjo, part no 13 31 1 266 616
Note: BMW supplies hoses with a new design banjo couplings these days. In the case of the cold start injector I found that this hose was under some tension so I used the slightly longer 13 31 1 266 616 WUR hose instead.

Re: Cold Start Injector Pipes?
Many thanks for the information.
I'm still a bit confused, I have found 2 pipes in my big box of bits but I think there are three:
One from Fuel distributor to warm up regulator
One from warm up regulator back to the fuel distributor
One from Fuel Distributor to cold start injector
So I should order:
1 x 13 31 1 266 617
2 x 13 31 1 266 616
Is that correct?

Re: Cold Start Injector Pipes?
See above, 3 indeed. I'd order what you suggested, that's what I used. And all the o-rings, two for each banjo bolt!

Many thanks Jeroen
Re: Cold Start Injector Pipes?
The dealer wants over £150 for the three pipes!
Does anyone have a more cost effective alternative?

Re: Cold Start Injector Pipes?
You might have luck with a diesel/ petrol injection service specialist, they may be able to supply new piping and help swap over banjo fittings for you. I have some nylon air tubing that have used for gas supply to mig welder but unsure if this suitable for fuel, this piping I only know the outside diameter of, not inner. Its also used for air braking on hgv's.
Hope this of some help getting you there, thats what id try if stuck. Can still let you borrow mine til yours replaced..just let me know

Re: Cold Start Injector Pipes?
I ordered mines from the dealer as few years ago, in order to retain original looks. But for most hoses the original design is not available anymore anyway, meaning it is well worth to have some made by a specialist indeed, and probably save two thirds on the price.

Re: Cold Start Injector Pipes?
Many thanks for all your help and suggestions and also the offer of a loan. I think I'm going to try and have some new ones made up.
