Fuel lines
« on: September 01, 2020, 19:11:57 »
I am installing the refurbished fuel pump from my 230 SL and bought new fuel and brake lines.
For underneath the bottom I made and found some usable pictures of the position of the lines and how they are connected. But at the front of the car I am not quite clear about that. Can anyone show pictures of the position of the brake and petrol lines in the engine compartment?
Thank you in advance, Eric.

I can take some pictures later today, if the rain stops. In the meantime, please allow a question: Where di you buy the fuel lines? Were they pre-formed and cut?

My experience with Mercedes fuel and brake lines has been, they come in a roll and you have to unroll the roll and carefully match it to the old lines.
You might need a line bender so that you do not kink the line.
Also I have found out on my Mercedes cars is that the fuel lines for feed and return are different mm's. Be careful.

Perhaps these might help you. Let me know which area you need to see.

Thank you very much!
The next question is how are the brackets mounted?  :o
There are holes reachable from above the floor but some are in a closed compartment.
So what kind of bolts are used for these brackets?

Again something else.

I found these bolts before, but you still must be able to reach the holes from the upper side which is not everywhere possible.
And not every hole is square.
Or am I missing something?

Some of them use hex headed sheet metal screws where the bracket falls into a boxed section.

If you are making your own flares do the flares for the engine ends before you install the lines.  From experience trying to get enough torque the flare a 10mm line next to the frame and engine really sucks.

From the parts list I see:

N 000085 006124 SCREW Replaced with N 007985 006133
then   
N 007985 006133 SCREW FUEL AND BRAKE LINES TO FRAME FLOOR UNIT 3pcs

I also see

A 120 420 02 27 SCREW W RECTANGULAR HEAD FUEL AND BRAKE LINES TO FRAME FLOOR UNIT 1 pc (this is the one shown in post below)

And I got a bit confused as 1 of those latter ones is needed for fuel pump bracket to trunk floor fixing. This would suggest that this 1 piece from parts list is for fuel pump rather than the fuel lines. But I am not sure if this is true.

I see just tapping screws in the parts list for the front support fuel line fixing.

My thanks to you, Naj, as well. I am in the midst of doing these brake, fuel lines and brackets myself. Photos at Motoring Investments were helpful but yours are much better. Thanks again. Lee
