Just been reading a magazine with a bit about IVA's and it says all fuel pipe needs to be marked. I've just bought some 8mm microbore copper heating pipe for the fuel lines. Have i wasted my money?

I believe it means all fuel HOSE needs to be marked. Metal pipes are fine.

^^^^ Wot he said

OK cool, thanks guys.

Copper is not a good metal to use. It work hardens and suffers from fatigue. The stuff you want is a copper/nickel alloy called cunifer. It is also resistant to road salt unlike copper and is easier to bend and flare!
