Please could anyone help with the following problem?

I have a 1956 Ford Popular 103e..(that's not the problem by the way Smile

)
I have owned the car for 11 years now, it is totally original and standard, it has never let me down.
Just recently I have had running problems which seems to point towards foreign bodies getting into the fuel system.
This has only happened recently and last sunday coming back from my Parents house some 60 miles away, it started playing up and cut out quite near to home Sad

To cut a long story short, I found black debris in the fuel pump.
So my thoughts are that there is a short length of Braided hose from the fuel line to the Pump perhaps the Rubber tubing inside has started to perish and break down.
Does anybody know the construction of these hoses?
Do they have a rubber tube inside?
I have a new one 'in stock' but want to pin point the problem first.
Obviously the other options are:

Contaminated fuel from the Filling Station.....I have filled up 3 times now, all from different stations.
Someone could have dropped something into the Tank!....Nice!
or just muck from the walls of the inside of the Tank..but what I have seen of that, there is nothing 'Black' in there anymore Smile

Sorry to go on for such a simple question but thought it best to give a bit more information Smile

Thank you
Greg

Braided Fuel hose is just rubber inside and its notorious for collapsing internally especially if subjected to suction. The black bits are an early sign of this

Modern stuff is better a more suited to unleaded petrol

Vehicle Wiring Products stock it - clips and ends

Hi Phil, thank you for your reply, I think it confirms my suspicions Smile

and as it's 55 years old, its done quite well and possibly time to renew Smile

All the Best,
Greg

You can also buy braided hose with modern materials (Teflon) that last longer than rubber..it's not silly expensive either but be sure you buy from a recognised rally/race supplier (and preferably made in the UK or USA) as some of the eastern stuff isn't all it claims to be.

Unleaded petrol is notorious for rotting rubber fuel lines, a friend used to supply parts for aircooled VW's and said that demand for rubber fuel pipe had trebled after unleaded petrol became the "norm". Also I was at my MOT station a couple of years ago and a guy came in for a service with a MG TD, he confirmed that the braided hoses were breaking up after a spell of unleaded use. Nasty stuff. Shocked

It's not just unleaded, the Ethanol is causing problems and will get worse in a couple of years. Replace any fuel hose with J30 R6 or R9. (R9 is injection pressure rated).

I find the new fuel pipe more difficult to seal on the ends so I use new Jubilee clips when I replace it.
