Fuel lines

Post by max »

Hi, I'm going to replace the fuel pipes from the tank to the pump. Can anyone recommend where to get it from? Or if I should replace like for like, or use something else? The original looks like it aluminium.
Any advise would be great.
Cheers

They are 8mm steel pipes, i've just replaced mine with 8mm copper pipe. Get a pipe bender is it's easy to kink this stuff.

You'll need to take your tanks off to do it, and don't forget to flare the ends so the rubber pipes can't slip off.

Thanks Jacko. I might use copper myself. I've got some cheap bending and fairing tools. But I have been thinking of getting some braided stainless stuff. I don't know?!

You should take some pics as you do it so we can get a photo tutorial up! Especially if you're replacing the fiddly bits behind the fuel tanks etc. :)

Dutch member Wondermike composed a nice grocery list a while ago for the entire operation. All hoses can be replaced rather easily using the cover under the rear seat and a garage jack. There's only one breather hose on top of the left side tank half that requires that half to be removed. Piece of cake though, only three bolts and the large connecting hose. Make sure it's empty though 8)

Tank sender/pick up rubber O-ring 16121150391
Hose between filler and tank 16121176793
Connecting hose between tank halfs 16121176795
Breather hose to breather tank 134cm 16121177553
Breather hose left side tank 1 meter 16121176440 *
Y-connector breather hoses 16121115537
Hose pick up to fuel pump 1 meter 16121176440*
Fuel hose 8mm 1 meter 16121180409

* 16121176440 used on different places, a total of 2 metres is sufficient.

Hose between breather tank and blue overflow hose 6mm 13311272750
(also use abt 7cm between plastic line and steel line above right tank.
I personally left the breather hose from the breather tank to the filler to retain original looks in the trunk, that hose is also less prone to wear anyway.

Hose clamps:
18-24mm (4 X) 07129952109
15-19mm (8 X) 07129952107
09-12mm (5 X) 07129952102
42-48mm (2 X) 07129952119
37-43mm (2 X) 07129952117
12-15mm (6 X) 07129952104

And last one for now are the rubber bushes used for the fuel pump (etc) brackets: (3 X) 16121177891
Check lines between the pump, pressure regulator and fuel filter as well. How old is your fuel filter anyway? :wink:
