Hi Folks,
I wonder if you can help in checking my fuel tank for water I noticed a section of what looked like fuel hose laid in the bottom of the tank I used my spring "grabber" and lifted it out. It is 60 mm long and about 12 mm in diameter and is solid not a tube with a slit along the whole length. My immediat thought was a bump stop to be slipped into the edge of some sheet metal to protect the edge or protect something from the edge. It was rubber and clearly the type of rubber that is intended for continuous fuel immersion since it was not in the least denatured by being immersed in fuel. Any comments on what it is?
Regards,
K-BIKE

Would it be the hose #15 hooking up on the fuel filter?

Hi,
It was not a tube it was solid rubber with a slit all along the length. The slit depth was to about half way and it looked like it was clearly formed like that as if intended to fit onto a piece of metal plate so as to make a bump stop or stop the edge being sharp when something presses edge on to the metal.

Maybe it was placed there by a previous owner. Mine has no such protection device.

Hi Folks,
Thanks for your suggestions, when I was in my local dealers last week I popped in to the workshop and spoke to the two mechanics both very experienced BMW tecs of many years standing, who also maintain all of the BMW bikes run by the local tax collectors (Police). They both looked closely at it and given around 40 man years of experience between them neither had ever seen such a thing on any BMW so it will have to go down as one of life's little mysteries.
Regards,
K-BIKE

Anti vibration mount for the fuel pump mounting bracket. There is one on each side.

When I dismanteled my tank I found that the rubber (Nr.3) on crazy frog's thumbnail was falling apart.
It looked like jelly.
It was quit a rubbery mess in my tank.

Greetings
Bart

Hi a couple of weeks ago bought a spare tank off ebay,itd been stored for x amount of years ,that bad i had to let it stand for a week after drilling out cap retaining bolts to access pump etc,any way i had a bit of piping like you say that came out split down middle abit like lagging apart from this onewas just a mush where all the petrol had soaked in,i just put it down to in the begining living on the float arm and coming off.The fuel cover foam rubber was in such a stae as well,the filter gauze having taken some of the "discharge" off the insulator rubber(which is no 3 in diagram,Dont know if elles got one will let you know as am not refueling so i can put new fuel filter in.

it is a rubber buffer which slides onto the sharp edge of the fuel pump holding bracket, probably left side, to stop it from piercing the tank side in an impact
