Copper fuel pipe
considering using 8mm copper microbore (central heating) pipe for fuel on my car.Only running carbs so no need for high pressure stuff. What does Mr
SVA (or MOT) for that matter have to say.
The pipe in question meets and exceeds
BS 2871-2 1972, BS 2871-3 1972
and is EN 1057 Table W annealed rated
all Dutch to me
In addition to this is copper suitable for petrol. I would have though so because a friend of mine bought some replacement pipe for his Cavalier 4 x 4
turbo from Vauxhall and this was soft (hand formable) copper stuff ?
any thought ?
thanks

I have no personal experience of copper petrol pipes (all production cars have steel or plastic), but the last time this was discussed, it was decided
that copper reacts with the petrol and causes them to sulphur up or something else equally nasty.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

I did a bit of Google research on this: there's only a problem if you use low-grade '3rd-world' petrol full of sulphur in copper
pipes.
Petrol to European standards doesn't have the same problem.

Our petrol being OK would match up with Vauxhall using it. But what about MR SVA
I can only find the following:
The fuel system, including the tank and filler cap, pumps, filters, pipes and pipe
connections, will be checked for leaks, security, suitability for their purpose, and
positioning.
Particular attention will be paid to the positioning of components to minimise fire risk.
Every component must be securely fitted, made of suitable materials, protected as
appropriate from corrosion and heat.
Thought I had read somewhere about appropriate markings ?

My car passed 3 years ago with aforementioned 8mm pipe and has had no problem with it since.
yours, Pete.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Thanks Pete,
Did you flare the ends to connect to the rubber hose or did you us some other type of connection ?

I just used compression clips as there is only gravity pressure till the block mounted fuel pump. I use an inline filter in the hose leading to the
pump from the copper pipe and it has only blocked once due to welding residue from the home made tank.

Thanks, I will either flare the ends or solder some plumbing compression rings on
Inline filter forgot about that one.

I used the 10mm mico bore on a previous project. No problems at all. Didn't flair the ends or anything. Just used clips. Was OK and passed
SVA no problems. Just make sure you put enough proper clips in it and clip it to the chassis. Clips no greater than 30mm appart.

bought some pipe today,
A quick experiment with a flaring tool (my brake pipe set from Lazer can flare pipes up to 1/2 '' ?), proved successful. So there is a job
for the weekend.
ps I have a bag of 100 "p clips" so will probably fix it every 200mm anyway.
thanks
