Well men whilst I had the car up on the ramp at work recently I noticed that I was missing a plastic fixing on the drivers side skirt / sill cover and it appeared rust maybe the cause. So what to do, half term was approaching so I added it to my "to do" list. Well half term was last week and so i decided to investigate and as the picture shows you I was a little alarmed!
Rust a silent killer (of metal that is!)

I'm surprised your MOT station didn't mention those fuel lines last time it was tested.....
That's some nasty rust you dicovered - almost scared to look under my own skirts now....... -
Yes, Very sorry to see that
Note also the condition of the brake-lines and fuel pipes (and AHK lines). Mine were pretty much held together only by rust and no tell-tale signs when braking.
I've not removed the plastic sill skirts on my 840, but I did fill the sills with quite a few litres of cavity wax. However, as seen from your post, it's the underside that also needs checking.
The sill parts may be available from BMW, though it may be a big job to reweld. -
Lines are on my list, I did clear and paint them as BMW said its 10 days so I didnt want to wait. Easter break is the next work time.

Great work Lloyd! I'll not be removing the side skirts just in case.

Whilst you meantion it there are two lines on either side are they all fuel
No 1 & 2 but what are the other two in terms of part numbers etc. -

- Fuel feed line 16 12 1 180 336 (V12 only)
Right side:
- Fuel return line 16 12 1 180 337
- Vent pipe 16 13 1 182 051

Found rust on my drivers side sill as well in 2010 and had it done. Fuel lines were replaced then as well as my MOT station had mentioned they needed attention 2 years running.

This a daily year round driver????
My 90 model has virtually no signs of rust anywhere.
I had the typical sunroof issue when I bought the car, and I have seen some very small spots (pin head size) in the bottom edge of my doors.
Other than that there is nothing worth mentioning.
My car has probably not been winter driven the last 10 years or more, and a previous owner had a corrosion treatment done in -96.
Just curious if you drove your car on salty winter roads, lived by the coast or something, because rust does not appear to be an issue on Norwegian cars, but they are usually not driven in the winter. -

Surely it would be more cost effective to buy S/S pipe and make them up myself in the workshop as I have all the tools?
Sorry I can't answer query about the spec, but can confirm that I found it cheaper doing it that way. (£40 each sounds very cheap to me, i thought they were more than that..)

Early cars ('90-'91) were better as BMW used steel with lesser quality on later cars.
Driving on salty roads is of course a major contributor to rust.
I actualy hear the salt chewing on my car every time I go down the garage...
Cheers,

Sorry Lloyd i don't know..the fabricating was done by my garage. If nobody chimes in with the answer i will try to find out but I am guessing they used the existing pipes as a guide and may not have kept a note..

BB I will get the digital caliper out tonight and have a measure. The fuel line that is

Steve there was a collection of wet mud/road dust built up between the sill and the skirt which meant that was constantly wet and touching the metal hence the rust I believe. Either way its all solid now.
Just measured the fuel lines 8mm O/D so I may order some S/Steel tomorrow just need to track down the flaring tool and bender.
