What size fuel pipe?
nib1980 - 20/9/06 at 08:01 PM

Hi all,

I've just fitted my brake lines, and am moving onto the fuel line now. What size pipe do you all use? can i use the same as the brake lines?

I'm running twin 40's on a xflow

many thanks in advance

I used 8mm bore which seems about right

8mm microbore central heating copper pipe B&Q cheap for loads but carefull when you bend it, may be worth getting one of those small hand pipe benders for the tight turns. I destroyed half the pipe by bending it to far.

Allens Motor Services in Arthur Street sell 8mm copper pipe by the foot. It's not expensive. If you need any plastic P clips to fit it I've got some you can have.

NO!!. brake pipe I.D. is tiny.

As folks said, either copper tube, 8 mm minimum I.D. or rubber hose. If the latter, it has to be marked suitable for petrol.

re: copper and fuel - there as some post somewhere (narrows it down a bit) that copper knackers the fuel injectors ... but that would be very high mileage and doubt any one here needs to worry about that, so go for it.

try tifosi, sells a really nice very lightweight fuel pipe (about 9mm ID) seems to be some kinda alloy and its got a very thin plastic protective coating over the pipe. Bought ages ago but seem to remember it wasnt that dear. Maybe not as cheap as B&Q copper though

You're wrong well kind of anyway... there was some concern from professional fuel systems/fuel additive designers that over a long period of time (i.e. production car milages) it would cause injectors to gum up. Most here have used it with no reported problems.

No safety problems, well SVA are happy with people using it anyway.
