Fuel Pipe
Question, if we use special coper pipe for brakes, should we use special copper pipe for the fuel line?
Ebay has an auction of 8mm fuel 'ford' pipe. I was just thinknig if plain copper is ok, I could go and buy 8mm central heating pipe.

many people have used std heating copper pipe. there is a school of thought that says copper reacts with fuel to produce sludge, but its been said on
here that only counts for low grade fuels........

We used small bore (10mm) not microbore (8mm) as the ID of the bike pipes for our engine are 10mm.

Hmmm, looks like I might be popping off to stewarts heating and plumbing supplies then
2m of 10mm, 2 olives and some solder has to be cheaper than the bloke selling 5m of the stuff inc postage for 10 pounds.

I am a little concerned about the SVA with microbore, should the pipe have special markings indicating fuel usage?
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

most rubber fuel pipe I have seen is 8mm internal bore.... so using 10mm pipe might make life hard.
whats the dia of the engine end it connects to? you dont wanna be connecting 10mm hose to 8mm fittings.....

ps - even my 'big' 2.4 V6 is fuelled by 8mm

Sierra uses 8mm throughout, so as soon as the marking thing is cleared up, thats what I will use

I used 8mm copper, no problem, and 3/16th copper for return pipe.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

i bought 4 meters of rubber hose for around 10 to 15 squids. more than enough and easily flexible. still, whatever tickles your plums!

Note for the safety nut:
Metal fuel pipes should be connected to (electrical) ground at some point. The flow of fuel can build static charges that cause sparks.

Hmm, interesting comments. One of the reasons I wanted to go copper was cause i've got a long term plan (heck, this cars 4 years in the building
already) to convert to Fuel Injection. I thought it would be easier and cheaper to plum in two fuel lines now and then add the fuel injection proof
rubber when needed than shell out for all fuel injected rubber now.
Where did you get your fuel hose from for 10 to 15 pounds and was it high pressure hose?

Steel fuel pipe on cars isn't earthed. If something runs to earth that's what causes sparks isn't it?

Just realising i'm being a complete muppet. One of my mates is an engineer for BMW and ...... works on the fuel tank / fuel supply line side of
things !!!
I'll ask him and get back to you all (if he's not disappeared to china for a month)

IIRC the rubber fuel pipe has to be marked up as fuel pipe compliant or other I.D. (IIRC)
Regarding the 10mm OD pipe - our bike fuel pipes were 10mm ID that's why we used 10mm. If sierra is 8mm then it makes more sense to use 8mm.

Pete, don't get confused with earthing something that is directly connection to a live source - that will cause a spark.
For confirmation of fuel flow causing static electricity build-up have a look at an HGV fuel tanker the next time one is delivering to a petrol
station. They have a thick Earth Bonding Cable which they attach before fuel is pumped.
In regard to earthing the fuel lines, I am sure that it will be unintentionally earthed along it's path to and from the tank / engine anyway.
Please come and visit me in Princess Royal Hospital's burns unit if I am wrong. (Grapes not Flowers please).
Regards,
Rick
