Fuel pipe
« on: January 30, 2026, 08:59:26 AM »
I bought some fuel pipe on fleaBay 18 months ago and it’s cracked..

I contacted the seller and they said the one I bought wasn’t guaranteed 
and sent me a link to this one, but it £27 per metre!!!

Does anyone have any better leads of better value pipe?

I can't offer an answer and it is a quest I am currently on.  I keep buying different petrol pipes and all seem to have the same problem. 

I have got some cloth covered tubing which is better in that it keeps the UV off the rubber but it still splits where it joins my fuel filters as that bit is exposed. 

I was wondering about switching to the clear plastic pipe that has a fabric mesh running through although this doesn't look as good as the black rubber type.

Let's hope some combined knowledge might bring about a solution.

Thanks for the replies.

I got hold of some reinforced fuel pipe is 5.4mm ID, and it wont fit on the fuel tap.

The measurements for the fuel tap are 6.95mm on raised bits and 6mm on non raised bit.

So the question is, do I have the wrong fuel tap?

Also you can see in the background of this photo, from the fuel tap to the carbs there was a small piece of fuel pipe connecting to joiner pieces, which I presume has been retro fitted because the previous fuel pipes at fuel tap end were damaged.  I presume it is better to have one continuous fuel pipe? This must have been done because replacing the the length of pipe is a pain.

Shouldnt be joiners and Honda never used that style of hose clip.
Reinforced pipe will be too tight

Thanks Bryan!

Is the fuel tap size correct do you think?

The genuine Honda stuff you have is spot on, and bends correctly?

The last time I bought some black fuel line, I got it from a large Briggs and Stratton dealership. It was quite a few years ago, but they did have a range of diameters, and it was good stuff.  You have to rewind your brain though, as it's American, it's sold by the foot!!
