Now the fuel hose has perished!
Guinness - 11/4/09 at 02:35 PM

Got the K-seal in the cooling system, parked the car up outside, on tickover to warm it up and took a look underneath.

Drip, drip, drip. Quick smell of the liquid and I realised it's the stuff that costs £1.00 per litre.

Took the transmission tunnel cover off and the front 1m section of fuel hose is leaking. Worse than that so are the contacts on the back of my FIA switch! Gulp.

Been round to the factors and got a new length of fuel hose. Seems OK now.

Anyone using the fuel hose with the cotton overbraid from Halfords, check yours out!

Not having much luck at the moment are you!!!
Replaced all my fuel line with cotton overbraided hose from Demon Tweeks over winter, looks better but will keep an eye on it.

Just done mine with goodyear rubber as its stamped for fuel use.

Whats the life of fuel hose ?

Two or three years, in my case! Rescued attachment fuel-pipe.jpg

WOW

Thats fecked

Thats why it's not a good idea to use rubber fuel hose down the tunnel.

on mainstream cars the hose should last the life of the car....looks like someone is selling dodgy stuff


greggors84 - 11/4/09 at 05:04 PM

Had to replaced some of mine too. Just seems to go hard then perish and leak.

Luckily I used 8mm copper microbore for most. Just small lengths to the tank and carbs.

Have had to replace mainstream car fuel hoses plenty of times

This just goes to reinforce the argument the SVA have of insisting the fuel hose is corectly marked as to it's purpose.... leaded, unleaded, injection, normaly aspirated,
forget which one it is but there are chemicals in one type of fuel that will rot the pipe of the wrong type

I also had to replace mine a few weeks ago due to a small leak.

I think that's what did my original pipe in - I reckon that it was general-purpose old stock from the motor factors that wasn't up to the unleaded standard. There are some nasty chemicals in modern fuel, including benzine!

It's actually quite hard to find a length of fuel hose properly marked for unleaded - unless you know the exact standards codes.

Codan fuel hose, which most motorfactors stock is correctly marked for unleaded and is rated up to about 12 bar IIRC.

I used that on mine and it seems to have been ok so far. I always have some spare in the boot though just incase, and its all somewhere pretty easily accessible.


Guinness - 11/4/09 at 08:46 PM

My original fuel hose was from Halfords, marked as fuel hose, in a lovely package that couldn't be mistaken for anything else other than fuel hose. It even had markings on the pipe saying it was fuel hose.

It passed SVA with this fuel hose fitted.

Now 3 years later it has perished. Either it isn't suitable for purpose, or it has a limited lifespan.

I have replaced it with a length of fuel injection compatible hose from my local factors. We'll see how long this stuff lasts, but fuel hose inspection will now be added to my list of pre-flight checks!

cheers

BS EN 228:2004 or the more recent BS EN 228:2008
Automotive fuels.Unleaded petrol.Requirements and test methods

Is one of the bits of numbering it should have. Guess there will be an equivalent US standard which would also be suitable assuming their unleaded is the same formulation as Europe's.

Presumably there should be a suitable OEM part for some car which is correctly marked, a suitable length and not unreasonably expensive.

Rubber fuel hose? Shouldn't they be some sort of unperishable metal?

A hose normally means that it is flexible whereas a pipe is rigid. I have never seen a metal hose!


Ninehigh - 12/4/09 at 06:59 PM

Pipe, hose, either way didn't think fuel lines would be made of rubber

How would you get the petrol to the engine (and from the tank) using a solid line? Vibration would cause it to fracture in 10mins flat.
Now the main run down the middle of the car is probably best done in metal, but you do need something flexible at the ends.

This is the same for tin-tops etc as well.


Ninehigh - 14/4/09 at 07:22 AM

Now that you mention it I remember a rubber fuel line on my escort chucking petrol all over the nice hot engine... Cost £90 to get from Buckingham to Warrington, and that's 1998 price too!


MikeRJ - 14/4/09 at 02:08 PM

It's not rubber as in the stuff made from latex, it will be a synthetic nitrile material.
