Fuel line

[Martinb2347]

Hi all,

We have just changed our fuel filter and noticed by accident what appears to be a break in a pipe underneath the rubber tube thing circled on the attached image.   We havent noticed any fuel leaking but wonder if this is normal

No, its not normal and if a BSS examiner finds it is as you say its a fail.

 

As the pipe is so close to the filter head it may just be slid over the pipe as a protection measure with no break in the pipe.

It may be to prevent the fuel pipe vibrating against the adjacent metalwork,and perhaps fracturing in time.

Update on the fuel line.   It is indeed normal and we have been sent a replacement Lister part which includes this as standard.   Our issue is the rubber sleeve is worn and sadly split so probably drawing in air.

Not if the copper pipe I am sure is inside the tube is still intact. Copper is not permeable to air. If it is a joiner as you seem to have claimed, then it is a BSS fail as per your original image.

 

Look elsewhere for the air leak. I would  suggest the rubber seal on the bowl of the filter as a start point or the same for the cover on the lift pump (if you have one).

As you have discovered, it is a Lister original part, I was hesitating before replying, in case my memory was playing tricks.
