Post by: nabsim on April 10, 2010, 06:07:07 PM
May be a silly question but is copper brake pipe okay to use for fuel pipe?

Shouldn`t be a problem they used copper fuel lines on beetles for years.

Thats a new one on me but then i havent had anything to do with beetles, i can say tho that steel pipe has been used for fuel lines for years.

Is brake pipe going to be big enough diameter for fuel pipe?  Don't want you suffering from starvation!!!

I will see what ID the brake pipe I have is. I saw copper fuel pipes on Minisport and just wondered if it was the same grade as brake pipe.

I use 8mm microbore central heating copper pipe for my car, brake pipe will be to small.

I'm planning something similar for Taz's trike too. Great Monkey minds think alike eh.  :)
Hadn't thought of using copper for the fuel lines though. The fuel doesn't react with it in any way then? I was just going to use it for the brake & water pipes.

you could use 10mm copper the same stuff that is used for oil boilers that is not affected by the diesel oil so cant see why unleaded shoule affect it

I've had trouble with copper fuel tube fatigue cracking if you don't strap it down to stop the vibrations.

I normally use P clips to hold it in place so never had that problem as yet....Voodoo....
