Well, it looks like I have been taken in! Fuel pipes should be reliable braided or otherwise. There is no guarantee that the one they send me will be safe.

If you go to a local motor factors as suggested, and buy a length of petrol hose there (with enough on the roll to do the job twice), you can be sure that it has been made to rigorous standards - just look what is printed on the hose itself.

I know you are being sent one for free but in future I wouldn't give the suppliers any consideration when it comes to consumables like this - they are more expensive and prove to be substandard.

Am I missing something here? I always thought that the braded type was correct fitment, not aftermarket. My series mm certainly had an original type with banjo fittings and that was braided. I might buy some standard hose to take as spare though.

If one company decided to do things properly, they would have the entire market to themselves....

Metal braided hoses are themselves not a problem - the braiding is used to improve the burst pressure (or reduce compliance) on high pressure hoses. Hence they are used on race cars braking systems etc.. and are often referred to as 'Aeroquip' hoses, although that's just one manufacturer and many others exist. They are also used on fuel lines as they give a better mechanical protection (and also to add 'bling') for a bit of extra protection.

The issue is not 'braided hose' - it is use of poor / wrong materials for the particular fluid.

Hoses that work with conventional brake fluid (e.g. EPDM material) are not compatible with mineral fluid such as oil & petrol/diesel. Conversely hoses for mineral fluids (e.g. nitrile / NBR material) are not compatible with conventional brake fluid.
Hoses that are cheap (e.g. PVC with a lot of junk & filler) shouldn't be used on anything safety critical!

Do you mean metal braiding or cloth reinforcing?

I've only worked on one Series MM recently and have already forgotten what the fuel hose looked like.
Of the one's I've seen, some a few had aftermarket hose - sorry I'm really not much help!

For Minor 1000 - many hoses were 'cloth' braided. I don't think any were metal braided hoses from the factory.

I found this pic of my old series MM showing the original type of 'Banjo' pump to carb pipe. It was a steel braid.

I might have one in the garage, if I find it I'll take a pic.

Of course, a lot of complaints come from the parsimonious owner who isn't prepared to stump up the cash to buy a part of really lasting quality.

But in cases such as this we have owners buying in good faith from 'specialist' suppliers and the goods don't last for very long. Same with repro chrome bumper blades. Vance Packard would have had a field day!

We are talking about a potentially lethal item here, poorly chromed repro bumpers are just not in the same league. I would gladly have paid more to have a good quality item especially when it concerns safety. Although it is very annoying to buy a new bumper and having it break out in rust spots after only a few months, having ones car go up in flames is far worse.

I work at a hydraulics distributor and we sell all manner of hose. Rayofleamington is quite correct, there are many types of rubber, resistant to different fluids. Motor factors will stock the correct hose for the correct application, speak to them for advice.
The braiding (steel or fabric) enables the hose to withstand a higher pressure, and also helps as protection.

Yes, but the fuel system in a (standard) Minor isn't high pressure! A rubber hose from the motor factors is fine for a standard Minor.

You're right chesney, I didn't explain myself very well :oops: :oops:
I meant the rubber hose from a motor factor will be correct, a braided hose just has other benefits

Just an update on this saga, I have today received a replacement fuel hose from the original suppliers. It is reinforced rubber and has the marking 'W=FUEL HOSE SAE J30 R6 SUITABLE FOR UNLEADED 1/4" ' Can this be fitted with confidence? Thanks and regards to all.

My local garage fitted a new braided hose for an MOT. less than 2 years later it had perished and over the winter it split into about 4 bits.
I wouldn't fit another one.
